There aren't any LVS defaults with regards to virtual/realserver
settings. I suppose this would be a good time to ask for the output from
"ipvsadm -L -n".
What tool are you using to run the test?
root# ./http_load -parallel 200 -seconds 60 ../ism_baseline.txt
OK, so you're simulating 200 simultaneous connections.
Do you get any errors in your Apache logs (assuming Apache server)?
no error messages at all
But then you say...
no, with two server at the same time I got the apache error:
[Mon Feb 26 12:47:27 2007] [error] server reached MaxClients setting, consider
raising the MaxClients setting
Not entirely surprising. Apache defaults (if I recall) to a MaxClients
setting of either 100 or 200, which you are going to exceed with your test.
Make MaxClients something like 500 and run the tests again. It looks
like your problems aren't LVS related, but application tuning is needed
