The main reason is that each cycle must extract records from the database (the Command speed is relatively fast)Use the GetRows () method:Copy

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

This article mainly introduces the speed test and comparison code for various encryption algorithms and Hash algorithms in PHP. If you want to select an encryption algorithm, you can consider it as a performance factor. For more information, see This article mainly introduces the speed test and comparison code for vari

Test and Analysis of the speed at which PHP collects data to extract core functionsAs the program requires, the execution speed of the core part of character extraction in PHP collection is tested.Three Common extraction methods are tested:Method 1:Require "class. debug. php ";Function getContent ($ sourceStr){$ Content = strstr ($ sourceStr, '');$ Content = subs

I tested the run time of fractional operations (http://www.cnblogs.com/YangXiaomoo/p/6095583.html) using the Ptime command under DOS. The test results are generally between 0.212 and 0.217. Such as. I then added the following code in the main functionThread.CurrentThread (). Sleep (1000);//Suspend threadAs a result, the entire program ran for more than a second, such as.SummarizeIn the program, the artificial addition of some time delay can make the p

The efficiency of foreach is much higher than that of for. a major reason may be that for has to perform many conditional judgments. So foreach can be used in the future, which can increase the efficiency by one time. Experiment is an important way for me to learn computer science. Computer science is not a simple intelligent game, but a tool to transform the world. Mathematical and experimental methods are the basic methods of computer research, and also the basic methods of learning. mathemati

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
