Re: [users@httpd] Apache utilzating Very High CPU

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,

Thanks for the reply..

Another information is, when the load test is being conducted we are
constantly getting the below error_log file of Apache

[info]server seems busy ( you may need to increase startServer,
min/maxspareservers) spawning 8 children, there are 0 idle & total 237
total children

What is the optimal value we need to set for
StartServer/MinSpareServer/MaxSpareServer for below hardware
configuration

2 (900 MHz) CPU/8GB RAM/4GB SWAP

Well, you could start by using a version of apache that has had active
development within the past 5 years or so.  2.2.3 comes to mind.

But in real world conditions, it is highly unusual for apache to be
cpu-constrained in any version.  For benchmarks, it all depends on how
you construct your tests.
