Hi Mark - I tried to test apache with stress test using JMETER and
results are not really good compared to sun one web server 6.1 running
on the same machine. ab results is good now (after I have used -k
option a suggested by you)
Apache jmeter test output -
count average min max stddev error% rate
bandwidth average_bytes
10000 253 32 2507 235.54 0 262.295082
4982.32582 19451
sun one jmeter test output -
count average min max stddev error% rate
bandwidth average_bytes
10000 111 31 1897 106.08 0 383.5532372
6779.228555 18099
i guess worker mpm should work better than prefork..right? I didn't
try prefork yet but do you think it's worth to check with that mpm
once? I have tried so many things to tune config but all the time no
better result than shown above for apache. You can see sun one web
server had better numbers in each fields.
could you or anyone else please help me further?
