Apache Threadsperchild and Maxrequestsperchild configuration analysis

The code is as follows

<ifmodule mpm_winnt.c>
Threadsperchild 1024
Maxrequestsperchild 10000
</IfModule>

Look at two references first

Maxrequestsperchild the total number of requests that a single child process handles during its lifecycle, when the total number of requests processed by a child process reaches this limit, the process is reclaimed, and if set to 0, the process will never expire (so that if there is a memory leak, it will always leak.) ...... ）
Threadsperchild the number of service threads per child process defaults to 25

The best way to configure my machine is as follows

Want to change the size of large maxclient more than 256, in the online forum to see, said added Serverlimit line on the line

The code is as follows
<ifmodule prefork.c>
Serverlimit 2000
Startservers 10
Minspareservers 10
Maxspareservers 15
MaxClients 1500
Maxrequestsperchild 10000
</IfModule>

Summarize

You have to calculate the amount of memory per httpd request, the number of requests per second after removing the memory consumed by the system and other programs, you can calculate
