On a stock RH9 apache setup, I think the max thread count
is 150 right??
=====httpd.conf===StartServer 8
MinSpareServers 5
MaxSpareServers 20
MaxClients 150
MaxRequestsPerChild 100
========================
Changing
MaxClients 256 (This is somehow the max that can be inputted
using redhat-config-httpd (or something like that)
-c 1000 yielded 53.69 requests/sec
-c 100 yielded 1020.12 requests/sec
-c 256 yielded 75.78 requests/sec
vs MaxClient 150
-c 1000 yielded 53.47 request/sec
-c 100 yielded 260.35 requests/sec
So.. What's happening here?
