mbs speed test

Let's test the network speed, which php does. It is definitely not an advertisement. you can help test the speed: http://www.hjsww.com.cn thank you. It is definitely not an advertisement. good = thinking is more important than skill =. I use AD, and the open speed is average

Time is used for timing. dd is used for copying, reading from if, and writing to. If =/dev/zero does not produce IO, so it can be used to test the pure write speed. Similarly, of =/dev/null does not generate IO and can be used to test the pure read speed. Bs indicates the size of each read or write, that is, the size o

The installation of protocol-based (for example, Gigabit Ethernet) networks boosts the rapid increase in the use of optical cables in Lan, which can meet the increasing bandwidth and transmission speed requirements. Multimode Optical fiber cables, especially for Gigabit Networks, and single-mode optical fiber cables as high-speed transmission media began to be laid in large quantities in buildings. Therefor

Label:1. Use PHP code to loop the data you want to insert into a file Random string function Getrandchar ($length) { $str = null; $strPol = "abcdefghijklmnopqrstuvwxyz0123456789abcdefghijklmnopqrstuvwxyz"; $max = strlen ($strPol)-1; for ($i =0; $i 　　 2. Run the load data local infile in the MySQL query to read the files written to the data, you can seconds such as the database million data LOAD DATA local INFILE ' e:/insert.sql ' into TABLE gc_customers (' FirstName ', ' LastName ', ' email ',

When Internet speed is found to be slow, people usually first test their computer to the network service provider (often referred to as the "last kilometer") network connection speed. In websites that can be used to test broadband speeds, speedtest.net may be the most widely used. Speedtest.net's work is not complicate

Sometimes when we do maintenance, there will always be similar to the IO is particularly high, but can not be determined to be an IO bottleneck or improper setting of software parameters caused hot disk problems. This is usually the time to know the disk read and write speed, to make the next decision.Here are two methods of testing:(1) using the Hdparm commandThis is a command that is used to get the parameters of the ata/ide hard drive and is writte

Time is used for timing. dd is used for copying, reading from if, and writing to. If/dev/zero does not produce IO, so it can be used to test the pure write speed. Similarly, of/dev/null does not generate IO and can be used to test the pure read speed. Bs is the size of each read or write, that is, the size of a block.

of HTTP requests Today's Web pages have multiple images, CSS external file links, JavaScript external script links. So when accessing a Web page, the browser needs to request these files to the server multiple times. There is a lot of time difference between the request and the load. In particular, some Web pages have multiple small pictures, icon buttons of the page, how many pictures, the browser will need to request how much these small files, many will request these small image files w

have been resolved for 0.1 million times, because my Shared Pool space is not large and contains a large amount of 0.1 million pieces of information. According to the FIFO principle, you can see that, all the SQL statements I have found are SQL STATEMENT records starting from more than 92000. We know that these SQL statements are similar and there is no need to parse 0.1 million times, that is, each statement is parsed once. This PROC1 does not use variable binding. This is where we can optimiz
