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
The StartServer/MinSpareServers/MaxSpareServers directives are not very important on real servers. It is really only on benchmark tests where you are going to see an effect. Again, the optimal setting depends on the specifics of your benchmark and what you have included in apache. In general, you want a big enough gap between Min and MaxSpareServers so that apache doesn't have to continually fork and kill children to keep in the appropriate range. StartServers is usually set equal to MinSpareServers, but can be set higher if you know that you are going to have a big load on the server right away. Probably the optimal setting for general benchmarking would be to set StartServers and MaxSpareServers equal to MaxClients and MinSpareServers equal to 1. That way apache would prefork everything it needs right at the beginning and never kill anything. But make sure that this fits in physical memory.
