Nginx Slower than Apache??
- by ichilton
Hi,
I've just setup 2x identical Rackspace Cloud instances and am doing some comparisons and benchmarks to compare Apache and Nginx.
I'm testing with a 3.4k png file and initially 512MB server instances but have now moved to 1024MB server instances.
I'm very surprised to see that whatever I try, Apache seems to consistently outperform Nginx....what am I doing wrong?
Nginx:
Server Software: nginx/0.8.54

And Apache:

I'm currently using worker_processes 4; and worker_connections 1024; but i've tried and benchmarked different values and see the same behaviour on all - I just can't get it to perform as well as Apache and from what i've read previously, i'm shocked about this!
Can anyone give any advice?
Thanks,
Ian
