I'm running redhat 9 in celeron 600mhz+ram 128mb+hd
7200rpm(maxtor)
while reading about http benchmarking, I running ab
and httperf to mark webserver:
I have a result that confuse me with result in redhat
AS2.1, there is big difference in "Transfer rate"(5x
slower) in ab
benchmark with concurrency level 1000 and connection
5000 while in concurrency level 100 the result has
nothing difference
so check with httperf with this command:
httperf --server localhost --uri /index.html
--num-conn 5000 --num-call 10 --rate 200 --timeout 5
and both have similar result, so what I have tuning in
redhat 9
tuning that I did in redhat9:
fs.file-max = 32768
kernel.threads-max = 5120
vm.bdflush = 100 1200 128 512 500 6000
500 0 0
vm.page-cluster = 16
vm.pagetable_cache = 25 50
(sorry if I have a long message)
