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

Copy the Code code as follows: Set_time_limit (0); $str = Str_pad ($STR, 512, "0"); $file = fopen ("./temp", "A +"); $i = 0; $bytes = 1000000000; $mygabyte = $bytes/1000000; echo "Test start.

Direct command speedtest_cli.

Usually we need to optimize the function, the general practice is to get the time at the beginning, the end of the time to get a second, two times to subtract time to the time to spend. And the function runs fast, basically is the millisecond level. The function given below is intended for this purpose. Time to timestamp (milliseconds) function Time2stamp () { var d = new Date (); Return Date.parse (d) +d.getmilliseconds (); } Usage: var T1 = Time2stamp (); Compares the

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

Experiment is an important way for me to study computer science, which is not a simple intellectual game, it is not a science in essence, but a tool to transform the world. Mathematical method and experimental method is the basic method of computer research, is also our basic method of learning, mathematics exercise our thinking ability, experimental exercise our ability to operate, solve practical problems. Our daily work should be seen as an experiment that summarizes what is useful to us from

Everyone help test the speed, PHP do. Definitely not an Advertisement.
