I have test the pound with web application stress tool,

in the 500 for the "stress level (threads)", and 1 for the "stress multiplier (sockets per threads)"

I assume it 500 user.

I test it for a while, the pound manage to survive, but some lagging for the 1st open up the site..

Then I try to test with 1000 for the "stress level (threads)", and 1 for the "stress multiplier (sockets per threads)"

And the web show up this error messages, "503 Service Unavailable"

in the pound log, i found this error (repeatedly)

     pound pound: error copy server cont: Connection reset by peer

     pound pound: error flush headers to 192.168.100.1: Connection reset by peer

     pound pound: error copy server cont: Connection timed out
     pound pound: backend 192.168.0.251:80 create: Too many open file

 

I had try to set the clients to 600, and set the ulimit

 

[root@pound root]# ulimit -a
core file size        (blocks, -c) unlimited
data seg size         (kbytes, -d) unlimited
file size             (blocks, -f) unlimited
max locked memory     (kbytes, -l) unlimited
max memory size       (kbytes, -m) unlimited
open files                    (-n) 999999
pipe size          (512 bytes, -p) 8
stack size            (kbytes, -s) unlimited
cpu time             (seconds, -t) unlimited
max user processes            (-u) unlimited
virtual memory        (kbytes, -v) unlimited
 

what should I do so I can achieve the best performance ?

do i need configure the sysctl?

Many thanks Kevin. These 73 requests/second are very much in line with
our tests and other reports we received.

Keep the reports going.
