Subject RE: Network is unreachable: connect to listener
Date Wed, 10 Jul 2002 09:47:32 GMT
I have just tried this and can't see any clear differences.
May be I am using ab to test and every request is served within 300ms
only.

Indeed any other good testing tool besides ab??
I need to test because there is request drop in my web application.
Those requests are my application's KeepAlive.  Dropping of those
requests will make my client to be interrupted.

Thx. and Regards
Steve.

Have you tried turning KeepAlive off? Do you get a change in the 
performance it you do?
