Become the richest man in the world starting from the rebirth of college entrance examination

At 8:30, Q Bar's employee who is responsible for monitoring the movements of Tie Bar friends reported to Xu Chengzhi: "The Tie Bar people announced that it is time to burst the bar, saying that they will all come to our place at 8:40 to burst the bar!"

Xu Chengzhi looked at the time and sneered, "Ten minutes is enough for us to be ready. The technical department has prepared for me. Starting at 8:50, within half an hour, all users who post in the Q bar will be permanently banned. Post!”

The employees in the technical department immediately stood ready, preparing to follow Xu Chengzhi's order to eliminate the opponent's effective forces as soon as possible.

If the accounts of millions of bar friends are unable to post in Q Bar, then they will have little fighting power.

Xu Chengzhi's hands were shaking nervously, and he seemed to be a little excited in his heart. His fists clenched loudly. I want to see what other methods you have available today. "

At 8:40, the number of logged-in users of Q Bar suddenly increased from 50,000 to 1.45 million, a sudden increase of 1.4 million people. You don’t need to think about it to know that these 1.4 million people What are people for?

The 1.4 million bar friends are very disciplined. They log in but do not post. They hibernate in their assigned Q bar, write the topic and content, and wait for the time to post immediately.

Time passed by, Xu Chengzhi's nervous palms were sweating, and so were the other employees. After this first experience, they all knew that victory or defeat could be decided in an instant. As long as they resisted the first wave, Q Bar would be You're sure to win, but if you can't hold it back, there's nothing you can do. The server crashes again because it exceeds its capacity, and there's nothing anyone can do.

There are still two or three minutes until 8:50, and thousands of people have already lost their patience and started posting. Thousands of people are nothing to the current Q bar.

As soon as 8:50 arrives, countless netizens in front of the computer give up everything they are doing and gather in Q Bar to start posting. Last time, one million people responded, but hundreds of thousands of people overwhelmed the Q Bar server. , and the rest didn't come in from the beginning to the end, but this time it was different. This time, millions of people posted at the same time. The system only lags in the first two minutes, and there is no problem that it cannot be opened.

Zhou Hao has been repeatedly opening the q bar webpage. Although the speed is a bit slow, it is not like the last time where he couldn't access it at all. This proves that q bar has indeed spent a lot of money to upgrade the server, which can host millions of people posting at the same time. not a problem.

Xu Chengzhi stared at the data closely, counting from 8:40 to 8:53. In these thirteen minutes, a total of more than 1.3 million posts were posted.

The content of these more than 1.3 million posts is basically to denounce Q Bar’s practice of shirking responsibility. The content almost all revolves around a few key points: copying Tieba content is obviously their official behavior, but they still find excuses and forcefully push it to It is extremely shameless to put the user's actions on their shoulders and let them take the blame for their actions.

More than 1.3 million posts means that more than 1.3 million users have lost their combat effectiveness, which is almost the majority of the force that will explode tonight.

Xu Chengzhi couldn't help laughing. He managed to hold on to the first wave of traffic peak of 1.3 million, which proved that Q Bar's server was very powerful and indestructible. The other party's 1.3 million users could no longer post, and the remaining The one or two hundred thousand won can't make waves at all.

He excitedly said to everyone: "Tieba has run out of tricks. We will definitely win this time!"

After saying that, he immediately ordered the staff: "Hurry up and delete the junk content they sent in batches."

"it is good!"

The excited employees also began to deal with the large amount of spam content that had just poured in, and the technical department began to batch send users scripts that permanently banned posting. There are more than one million users, and it will take some time to run them all.

The entire Q Bar Business Department was in jubilation. Everyone was full of energy and started cleaning the battlefield desperately.

Xu Chengzhi was high-spirited and called Mr. Ma who was attending an Internet conference in Beijing. His first sentence was: "Mr. Ma, Tieba has just planned another explosion."

Mr. Ma hurriedly asked: "How is the situation?"

Xu Chengzhi said excitedly: "The carrying capacity of our server far exceeds their expectations. There are more than 1.3 million Tieba users posting, and our server has no problem. Now we are setting a permanent ban on posting for more than one million users. "

Mr. Ma said with satisfaction: "We have done a good job, we must keep it up, and we must not let Q Bar have any mistakes again."

Xu Chengzhi said with great determination: "Don't worry, Mr. Ma, I will definitely do this well!"

While Xu Chengzhi was promising Mr. Ma enthusiastically, Zhou Hao said to Yan Hui: "Let's get started. Let everyone do a wave of brushing first to see how long their servers can last!"

Yu Yanhui couldn't help but laugh out loud: "Although their server did not crash, half of the posts just now were published successfully after a minute. The server response time was too long. We will face the next few seconds. I think he will be completely destroyed within a minute with just one message from the site!"

Zhou Hao said with a smile: "Hurry up and inform me, I can't wait!"

More than a million users who can no longer post in Q Bar are now receiving notices that are passed on to tens of thousands. When they learn about the latest method to explode the bar, they immediately turn on the in-site message function of Q Bar and prepare to post within the site. The letter was being prepared, but at this time, Xu Chengzhi and the entire Q Bar staff were completely unaware. They were still immersed in victory and concluded that Tieba no longer had any fighting capacity.

But I never expected that everyone changed their routine. They banned users from posting replies, but never banned users from posting messages on the site...

The technicians who were deleting content and running scripts to block accounts suddenly discovered that their execution speed began to become extremely slow. The script was running on the server. It could block thousands of users in one second, but suddenly it was so slow that it could only block accounts in one second. After running more than a dozen times, the speed of deleting content dropped to single digits per second. One of the technicians couldn't help but blurt out: "What's going on? The server execution speed suddenly slowed down so much?"

As soon as he finished speaking, the speed slowed down again...

At this moment, all the users participating in the explosion bar are using Q Bar's internal messages to send random messages to each other. They can publish an internal message in a few seconds, and in an instant, millions of internal messages are pouring into the server, and are sent by the server To carry out distribution and delivery, the carrying capacity of the server is immediately increased. If it is only sent in one wave, the server can still carry it.

But the key point is that the server executes millions of intra-site messages, sends, receives and delivers status information and then feeds back status information. This process takes at least ten seconds or even longer, but the second wave of users’ intra-site messages pours in within a few seconds and begins to send and receive. Queues are queued in the system for processing, which greatly increases the server's carrying capacity.

By the third round, only ten seconds had passed. Three to four million site messages had already made it difficult for the server to handle. It was also at this time that the staff of Q Bar discovered that the script running speed in the background suddenly became even slower. .

At this time, the server load is already very heavy.

They didn't have time to check where the problem was. Then, waves of in-site message requests poured into the server. As more and more in-site messages were squeezed, for the server, it was like a Double Eleven express delivery. It was like a warehouse explosion, completely overcrowding the warehouse.

The reason for server overload and logistics liquidation is the same. Originally, Q Bar had already set restrictions to strictly limit the total amount of influx every day. But what he didn't expect was that Zhou Hao changed his tactics. You don't accept the goods. Okay, then I won’t give you goods either. I will transport garbage to you. Anyway, the purpose is to fill up your warehouse. It doesn’t matter what you use to fill it up. Just fill it up.

Half a minute later, Q Bar's server was on the verge of collapse. Several technicians said in horror:

"It seems that suddenly a huge amount of data is being written, and the demand keeps adding up!"

"This is wrong! We have obviously restricted their posts and replies. Even if they re-register their accounts, these more than one million people will not be able to shake our server at all!"

"The background script cannot run at all!"

"The abnormal data on the server cannot be seen. It is almost stuck and even we cannot access it."

Xu Chengzhi's legs went weak and he could hardly stand. He was celebrating his victory just now. Why did the situation suddenly turn around? ! The server hung up right away, but who could tell me what happened? Which part went wrong?

Suddenly the technician suddenly shouted: "It's over, it's down!"

Everyone looked ashen. Compared with the excitement of the crowd half a minute ago, it was really heaven and earth.

Xu Chengzhi's vision went dark and he suddenly collapsed on the ground.

Seeing that the other party's server had become unresponsive and was completely down, Zhou Hao knew that his second attack on Q Bar had been successful. He wanted to celebrate, but his mind suddenly changed and he turned to Yu Yan beside him. Hui said: "Should we try to see how big the instant load capacity of the QQ registration server is?"
