Write speed:TIME dd If =/dev/Zero of = test. dbf bs = 8 k count = 300000Among them,/dev/zero is a pseudo device, which only generates a null compaction stream and does not generate Io for it. Therefore, Io will be concentrated in the of file, and the of file is only used for writing, therefore, this command is equivalent to testing the disk write capability.The output result is similar (because the test tim

0.PCATTCP Introduction The predecessor of PCATTCP is Test tcp,test TCP is the native tool of the BSD operating system, which is used to test TCP or UDP communication speed through console input parameters. The project was launched in 1984 and the source code for the tool is now open. PCATTCP is the Windows porting vers

Test speed is the most common and easiest to judge is to use some of the resources of the download software to download things to see how fast it downloads things k/s, to judge speed. The most accurate way is to use the Thunderbolt download software to download a few small resources to determine, if you download 3 to 4 mp3 songs, each MB (M) of the best bandwidth

How does your Mac test your hard drive speed? Hard disk is very important to the performance of the computer, because the computer speed is fast, in addition to CPU fast and memory is large, but also to see the speed of the hard disk. This is also a lot of small partners why so concerned about their computer's hard dri

I used the cms of the Empire to get a website and the cms of the Empire to test the speed. the mysql + php website is www.zhaodaoshi.com, the introduction and contact information of the graduate tutor and doctoral tutor feel that the system of the Empire is still quite useful. The problem is that it is too slow to add materials, I plan to analyze the database and write a small program to add news ., Good we

I did a test in two weeks. Maybe many Webmasters have done similar research. Two weeks ago, I updated the Forum at least two original articles with over 500 words each day. Baidu has taken effect on my new post for about three days. They all say that Baidu prefers high-frequency updates and excellent originality, which undoubtedly proves this result. During this period, Baidu's traffic to the Forum was at least 100 or 200 IP addresses. I started to

I spent 2 weeks doing a test, and maybe a lot of webmasters have done similar research. 2 weeks ago, I update the forum speed is at least 2 more than 500 words per day original. Baidu for my new paste included about three days effective, said Baidu like high frequency updates and boutique original, no doubt that is to confirm the results. During this period, Baidu brought the traffic to the Forum at least o

Php test hard disk write rate. Use php to write a 1 GB file, check the hard disk write rate, there may be some errors, it is recommended to use a professional hard disk testing tool to detect general computer read and write in 20 Ms, this is a 1 GB file written in php. check the hard disk write rate, which may have some errors, We recommend that you use professional hard disk testing tools for testing. Generally, the computer reads and writes at 20 M

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
