Re: performance issus, please help???

Thanks for the suggestion.
I ran some tests and used top to monitor my nginx server and apache backend server. During this whole test, i still had about 60mb free on my nginx server and 80mb free (85mb before test) on my apache backend server. I can clearly see that the free ram was slowly decreasing on the apache server as it was running. So i can see it working (aside from the new process spawns taking about 2.7% mem usage).

But why isnt it using up almost all the free ram?

here is my output:

#ab -n 30000 -c 50 http://xxx.xxx.xxx.xxx/index.html
