The test started, and as usual, the first company tested was the HD company that was number one on the list.

After HD engineers started the system, three Party A testers first checked whether the power supplies of other systems were turned off. Then they came to HD engineers and one of Party A's testers asked: "Ready?"

Is it ready? Can we start testing now?”

HD's engineer tapped the keyboard a few times, checked the system feedback information, and indicated that there was no problem and the test could begin.

A tester from Party A opened the test record sheet: "The first item, system load stress test, full load multi-thread concurrency..."

This person from Party A dictated the contents of the test case, and HD engineers followed the test steps in the test case to bring simulated end users online in batches and connect them to the system.

But when he just increased the system load to 50%, he suddenly found that the simulated user data fluctuated. The smooth straight line on the tester screen suddenly appeared many "burr"-like toggle, and as the load increased,

The amplitude of fluctuations has a tendency to become larger, but it is still within the allowable range of testing.

The HD engineer immediately broke out in cold sweat on his forehead, but the three testers from Party A were watching eagerly, so he had no choice but to bite the bullet and continue to increase the load on the system.

When the system load reaches 65%, the icons displayed on the tester screen can no longer be viewed. The data on the tester shows that a large number of data packets have been retransmitted and lost, which illustrates the current system load capacity.

The limit has been reached.

Seeing this, Party A's testers asked HD's engineers to stop the operation, freeze the data, and then start recording the data results.

"Okay, you can turn off the power. The next one, AC Company will start preparations."

Hearing this, Tao Jiang smiled at Gary, who was frowning next to him: "Gary, there's nothing to worry about."

Gary shook his head and said: "But the result of HD is obvious..."

"HD was obviously careless and not prepared beforehand." Tao Jiang interrupted him and winked at Gary: "And we have made sufficient preparations. You just need to concentrate on the test work. The rest will be fine."

Don't worry."

Gary didn't know why, but since Tao Jiang interrupted him and winked at him, he must have understood what the HD test results meant.

Gary didn't say anything more and directly started to start the system with his assistant.

Soon the test started. Gary looked at the smooth straight lines on the screen of the tester, his heart in his throat.

When he started the system, he quickly browsed the system configuration. He was sure that the configuration was absolutely optimal. Under normal circumstances, this smooth straight line would continue until the load increased to 90%.

If fluctuations occur and are directly loaded to 100%, the fluctuation amplitude will not exceed the range required by the test item.

This data has been verified by him many times. Before the HD test, he was very confident in this test.

But the HD actually failed the test. Although the HD's test score is not substandard, it is certain that the score will not be too high.

And Gary is very familiar with the phenomenon that occurred in the HD test just now. It is very likely that the system performance is degraded due to external co-channel interference.

It's like an originally four-lane highway, but two lanes are suddenly occupied by garbage. When the traffic flow is not large, the impact is not big, but as the traffic flow gradually increases, traffic jams will eventually occur, and the passing performance of the highway will decrease.

Therefore, this external co-channel interference is a problem at the physical level of the system. Although it can be improved to some extent through configuration optimization, there is no way to completely solve it. The only way is to test the terminal and remove the interference source first.

But obviously Party A would not do this. Even the HD, which had just failed the test, was silent at this time, obviously waiting to see before talking.

Gary can probably guess what HD is thinking. If all eight manufacturers test in such an environment, then the results are fair and their HD data will not be too ugly.

But is this really the case? In yesterday's test, only AC and Jianhai showed co-channel interference during the test, while everything else was normal during the test.

Therefore, Gary, who is focusing on testing at the moment, really does not dare to have too much hope in this "fairness" of refreshing the lower limit.

Fortunately, when the system load increased to 50%, the straight line on the tester still remained smooth.

Gary, who had been worrying about it, finally let it go. At least judging from the current test situation, the results are already better than those of HD.

When the load is increased to 60%, the straight line on the display remains smooth.

When the load increases to 65%, the straight line on the display remains smooth. It is not until the load increases to 70% that the smooth straight line begins to fluctuate.

Finally, when the load increased to 80%, the amplitude of the fluctuation exceeded the range of the test requirements.

The test stopped and Party A's personnel began to record test data. Gary sighed and stepped aside, leaving his assistant waiting to power off the system.

Seeing that Gary was in a bad mood, Tao Jiang walked up to him and asked, "Are the test results not satisfactory?"

Gary nodded, looking sad.

Tao Jiang asked again: "How does it compare with the HD just now?"

Gary said: "The test results are better than HD, but much worse than the results we tested in the company before."

"Such results are still acceptable. As long as the subsequent tests can be maintained like this, our final overall ranking should be one row ahead." Tao Jiang comforted Gary, but looked disappointed.

Look.

Gary looked at Tao Jiang doubtfully, feeling that he couldn't figure him out.

Party A's testers obviously had no intention of working overtime, and the pace of testing was fast. They completed the three tests in the morning in time for lunch, and then happily took everyone to the canteen to receive lunch boxes.

However, the personnel of the eight manufacturers all looked gloomy and gloomy, even AC and Jianhai, which had good test results in the morning, were no exception.

Not many people were in the mood to eat lunch, so lunch ended quickly, but Party A’s staff had good work and rest habits. After the meal, everyone was taken to a large conference room, and all Party A’s staff went to take a lunch break.

According to the situation in the past two days, it will definitely not appear before the test in the afternoon.

Not long after Party A’s personnel left, the tall and thin man in charge of testing from Blue Fire Company suddenly stood up and said loudly: “I believe everyone can see from the morning’s test that the test environment provided by Party A was completely unsatisfactory.

Standard, the data tested in this way is very inaccurate. I think we should jointly propose to Party A to retest after eliminating co-channel interference, or retest at another venue."

"I think Party A will definitely not agree to re-test. After all, there were no problems with the tests in the previous two days. Party A probably thinks that the impact of this morning's situation alone will not be significant. After all, everyone has been affected."

The person in charge of testing at Shengtang Company smiled and expressed his opinion. Obviously, his family did not agree to re-test.

Although his family was also affected by the test in the morning, after the three tests in the morning, his family's total score should be ranked third, higher than Blue Fire, which was last, and Daxin, who climbed one place ahead.

A lot. If his test results in the afternoon are similar to those in the morning, then there is no risk of him being eliminated and he will be firmly in the top three.

Retesting would not only be of no benefit to his family, but would also add more variables. His family would definitely not be willing to support such self-sacrifice.

The other companies' thoughts are similar to those of the Holy Temple Company, so Lan Huo's proposal is destined to be impossible to implement.

The person in charge of Wuda smiled and echoed: "I think there is really no need for you Blue Fire to mess around. Not only is it meaningless, but it may also offend Party A. Besides, the domestic electromagnetic environment is like this now, and the operator's 4G

After 5G is completed, base stations will be built everywhere, and the system

It is normal to be interfered with. Can you guarantee that after the system is built in the future, the system will not be interfered by external interference? Maybe the interference that occurred in the morning was deliberately caused by Party A, just to compare the situation in a harsh environment.

The performance degradation of each system."

The tall and lanky guy from Lanhuo Company immediately became angry when he heard this. He snorted coldly and said: "Don't stand and talk without hurting your back, Wu Da. You are the last one in line to see. I don't believe you are not in a hurry. You are so special."

You say it’s the interference caused by Party A, but I think it’s probably the interference caused by your family.”

The person in charge of Wuda was immediately annoyed. He pointed at the tall and thin man and said: "How do you talk? I just tell you my opinion. If you can hear it, you can listen. If you don't, just think I'm farting. You

Why do you bite back, are all you Blue Fire people born in the Year of the Dog?"

"Haha," the tall and thin man sneered: "Don't think that I don't know about you Wu Da. It's not like you haven't done dirty things before. If you don't want others to know, you have to do nothing yourself. You'd better remove yourself from a certain province first.

Take it off Zhengcai's blacklist and tell me this again."

The two families quarreled for a while, but were persuaded to leave by nearby people. The tall and thin man of Lan Huo glared at the person in charge of Wuda and sat down angrily.

But after sitting down, he was obviously still angry. He pointed at the person in charge of Daxin and said, "You'd better wipe your butt clean and don't let me catch anything."

The person in charge of Wuda smiled nonchalantly and said mockingly: "You'd better go back and fix your system first, so as not to be embarrassed when you come out."

After the two families made a fuss, everyone in the conference room had no intention of taking a rest. Most of them were quietly playing with their mobile phones, and only a few people were talking in low voices.

Tao Jiang saw Gary writing an email on his mobile phone. He took a peek and saw that the content was some analysis of the test situation. It was obviously an email reporting to Asia Pacific.

Tao Jiang did not disturb Gary. He left the conference room alone, found a secluded place, and dialed Zhang Wei's mobile phone.

When the call was connected, Tao Jiang smiled and asked: "Fat boy, have you had lunch?"

I don’t know what Zhang Wei said on the other end of the phone. Tao Jiang held up the phone and laughed loudly. He also said that he would be the host in the evening and would treat Zhang Wei to a big dinner.

After chatting for a while, Tao Jiang hung up the phone and was about to go back to the conference room when he saw the person in charge of Jianhai's test team smoking at the door of the building.

Tao Jiang hesitated for a moment and then walked towards the other party.

Arriving in front of Jian Hai, Tao Jiang pretended to touch his pocket, and then said with an embarrassed look: "Mr. Liu, can you borrow a cigarette? I may have forgotten my cigarette in the car, and I am too lazy to go and get it.

."

This man's name is Liu Qiang. The last time Party A organized a meeting for all the manufacturers participating in the final selection, the two of them exchanged business cards.

Liu Qiang didn't think much, smiled and handed Tao Jiang a cigarette.

Tao Jiang thanked him, lit his cigarette, took a puff, and asked seemingly casually: "Mr. Liu, how was your test this morning?"

Liu Qiang said: "It's not bad. It's not as good as your AC, but at least it's not inferior to small brands like Blue Fire and Marsh."

Tao Jiangdao: "Mr. Liu is still too modest. Jianhai has a very good reputation in the industry in recent years, and the two companies are still far behind. However, was there something wrong with your test yesterday? According to my review of Jianhai

Hai knows that the performance of your equipment will not be that bad."

Liu Qiang smiled and asked instead: "There must have been a problem with your AC yesterday, right?"

Tao Jiang nodded: "After we returned yesterday, we immediately held an emergency meeting. As a result, we couldn't find out the cause after studying it all night. However, according to the analysis of our technical experts, it was probably caused by external interference. This is our

Experts guessed based on experience that they can only wait until the test is completed, then call up the system log and slowly analyze it."

"Your experts' analysis is similar to ours. It should be caused by a co-channel interference source nearby when we were testing."
