the two functions confirms my idea that when the previous function executes, it reads all the result sets from the server side to the client side of the buffer, and the second one does not, which means "unbuffered (not buffered)". That is, if you execute a SQL statement with Mysql_unbuffered_query () that returns a large number of result sets, PHP memory is not occupied by the result set until the result is traversed. And with mysql_query () to execute the same statement, the function returned,

Recently on the memory of the program to do some optimization, achieved good results, summed up some experience, briefly said, I believe that we will write a good quality program to help The following discussion is for 32-bit systems that are not applicable to 64-bit systems, Often you write a program, a test, the function is no problem, a look at the memory footprint is not much, not to consider other things. However, it is possible that the progra

High memory Cause Analysis: In the 360 browser 3.x multi-process framework, memory footprint is higher than the single process, but the advantage is that the Web page will be completely free of resources after the page is closed.

MySQL View the size of the database and table footprint? Part I-Tasks After you export the online DB, import to Office dbOne.Two scenarios:1, the data directly from the Online-->office, through the mysqldumpTunnels are built via local putty and ECS, and then data is sent locally. (local win can be compressed and uploaded to Office Server by gzip)2, first on the ECS mysqldump compression, and then download it downDownload Solution:1,rsync

Many people like to intrude into Win2000, and there are also interface-based remote control such as 3389, so many vulnerabilities can be exploited, and articles about intruding Win2000 are everywhere, convenient. However, do you know what footprint you have left in the system? I recently made an intrusion analysis and found a lot of things. Of course, it is estimated that the intrusion time will be listed in the search file. Here, we will not analyze

Windows Forms apps are pretty bloated in terms of memory usage. the main reason. net apps have such a huge footprint is that the JIT compiler loads when the app starts and all that Bootstrap code and a ton of the winforms engine is loaded and compiled at startup and gets loaded into your process. beside the fact that this takes up processor cycles it also consumes a lot of memory. the JIT is pretty good about which code gets compiled-for the most part
