Subject [users@httpd] Apache 2.2 MPM Worker Virtual Memory Usage
Date Thu, 18 Oct 2007 13:05:15 GMT

There appears to be a significant difference between Apache 2.2 MPM 
Worker and MPM Perfork virtual memory usage. As well as between Apache 
2.2 MPM Worker and Apache 1.3 virtual memory usage. This can become an 
issue in a VPS (virtual private server) environment where resources are 
more constrained.

I am seeing 280MB vs 5.8MB of VM usage per process. You could argue that 
worker is supposed to use more virtual memory, as running multiple 
threads per process it actually uses less. But, that is not the case. 
Total VPS privvmpages is 2.1GB vs 358MB. What is really interesting here 
is why is it so much higher. You would expect some increase but it looks 
like most (if not all) of the virtual memory of each of the 7 worker 
processes is not shared. 7 * 280MB = 2GB. Which means it can't be code. 
I don't see how it could be this much code anyway. So then what is it? 
(Conversely most of the 2.2 perfork virtual memory is shared code. 150 * 
5.8MB = 850MB,which is more than 358MB for the entire VPS.) Is the code 
building some kind of large local process database? Anyway to turn it off?

Note I do have PHP or any other programmatic modules loaded. See below 
for configure info.

Thanks...
