I am attempting to do a bit of a comparison between nginx and apache
using httperf but my results are coming out a little strange. I am
running the following against both apache and nginx:
httperf --timeout=5 --client=0/1 --server=DOMAIN --port=80
–uri=/robots.txt --rate=200 --send-buffer=4096 --recv-buffer=16384
–num-conns=5000 --num-calls=10
The results I am seeing are the following:
NGINX:
Total: connections 5000 requests 50000 replies 50000 test-duration 25.001 s Connection rate: 200.0 conn/s (5.0 ms/conn, <=5 concurrent connections) Request rate: 2000.0 req/s (0.5 ms/req)
Apache:
Total: connections 5000 requests 10000 replies 5000 test-duration 24.998 s Connection rate: 200.0 conn/s (5.0 ms/conn, <=1 concurrent connections) Request rate: 400.0 req/s (2.5 ms/req)
Shouldn’t the ‘Total’ numbers be the same against both web servers since
I am using the same command to test them? Why is the ‘requests’ number a
1/5 of number that nginx responds with. Has anyone see this sort of
result in the past?
I have attempted this with a few different connection, rate and call
counts and seem to get similar results with each.
I have verified that my MaxClients and Servers setting in Apache is high
enough as well.
Thanks.
