The reason why the common Internet slows down The reason for this is that your broadband line is aging, or it is damaging (router) Reason two, if the computer and other computers share a network cable, it may be your computer by the ARP virus attack Reason three, there is a program secretly running the background of a large number of bandwidth, such as virus Trojan, Peer-to-peer software (Thunder QQ Whirlwind, etc.). With some other reason 1, the first need to check the network itself probl

How can we speed up Web browsing ?, How to speed up Web browsing? Despite the increasing bandwidth, the speed of Web browsing seems to be challenging our patience, especially during peak hours. How to Make surfing faster is always a problem that netizens need to solve. If you are a sogou browser user, you have more powerful tools than others. Let's take a look a

For a long time, the speed of wireless networks is the focus of users when selecting wireless devices. Many netizens raised a lot of questions about wireless speed when using wireless networks. For example, "I am using a XX-brand wireless router. How can I keep the wireless speed at 1 Mbps? My ADSL is Mbps, and the connection

One, the network exists the loop to cause the net speed to become slow This phenomenon rarely occurs when the number of nodes involved in the network is not many and the structure is not very complex. However, in some more complex networks, there are often redundant lines, such as inadvertently connected to form a circuit. For example, cable from the network Center to a computer room, and then from the computer room to the second room computer. At th

Every day, speed, speed, and doom. Full-level attributes: Doomsday: Maximum speed 458km/h, acceleration 15.5km/s, fuel-efficient efficiency 35.0km, gold coins added +10.5%, weight 720.0kg, variable speed +8.5%, Mileage added +10.5%, duration + 2 seconds Speed Track: maximu

4m Broadband download speed can reach how much? I believe there are still many novice friends do not understand, many friends mistakenly think 4M broadband download speed can reach 4m/s, in fact, this is very wrong, some time ago also for everyone wrote a: How to test the speed of the network of n methods, Inside introduced everyone some test broadband

Recently found around a lot of rice noodle friends, home since the ADSL upgrade to fiber optic network after a variety of slow speed. Today's small series to introduce how to improve and enhance the speed of the millet router. In short, it is how to let the cat and computer can match the millet router gigabit network faster speed. Now the fiber to th

(1) Improve the database insert performance Central idea: Try to write data at once to file and reduce the checkpoint operation of the database. The following four configuration entries were modified this time:1) Set the Innodb_flush_log_at_trx_commit configuration to 0, according to past experience set to 0, the insertion speed will be greatly improved.0:write the log buffer to the log file and flush the log file every second, but does nothing at tra

(1) To improve the database insert performance Central idea: as far as possible to write data to the database file and reduce the checkpoint operations. The following four configuration entries were modified this time:1) Set the Innodb_flush_log_at_trx_commit configuration to 0, according to past experience set to 0, the insertion speed will be greatly improved. 0:write the log buffer to the log file and flush the log file every second, but does noth

In the process of using XP, the system will run slowly over time. Some friends may think of reinstalling the system, but after reinstalling, so many applications need to be re-installed. How can we speed up XP without installing the system? As long as you perform the following nine operations, I believe your XP will run at high speed again.1. Speed up on/off When

Many people think that the bandwidth of 2 Mb is equivalent to the download speed of 2 Mbit/s, which leads to many misunderstandings. In fact, the transmission rate of data machines and network communication is generally measured in bps. For example, 28 kbps, 56 kbps, 128 Kbps, 1 Mbps, and 10 Mbps. Lowercase B indicates bit (BITs), capital B Indicates byte (bytes), and 1 byte = 8bit. Take the 2 M bandwidth as an example. For example, the download

CPU is the core of the computer hardware, but also the computer hardware in the heat, so the CPU cooling fan speed, the fundamental computer cooling. What about the CPU fan speed? Generally you will choose to see the BIOS settings, but the BIOS needs to restart the computer, and the operation is relatively complex. Today, the WiFi sharing master teaches you a very simple CPU fan

Mysql database insertion speed and read speed adjustment record bitsCN.com (1) thoughts on improving database insertion performance: Try to write Data to the Data File at a time and reduce the checkpoint operation of the database. The following four configuration items are modified:1) set the innodb_flush_log_at_trx_commit configuration to 0, and set it to 0 based on past experience, which greatly improves

Label:Requirements: Due to the project metamorphosis, it is necessary to dramatically increase the database record in a relatively short period of time (two or three days, due to 0 increase to 500 million). During the whole process tuning process is very difficult Ideas: 　　 (1) Improve database Insert performance Central idea: Try to write the data to the file and reduce the checkpoint operation of the database once.

Animation speed (buffering 10.1), animation speed buffering 10.1Animation speed Animation actually changes over a period of time, which implies that the changes must follow a specific rate. The rate is calculated by the following formula: velocity = change / time HereChangeIt can be the distance between an object's movements,TimeIt refers to the duration of an an

First, the realization of wireless rate 300M Wireless Router to achieve the actual 300Mbps wireless transmission rate? The answer is no. The wireless router's own 300M, 450M and other labels, refers to the router theoretically the maximum wireless transmission rate. In the actual transmission, even in the ideal environment, because the wireless connection is a Half-duplex transmission mode, the same time only allow one side to transmit data, so the wireless transmission rate will be reduced.
