Subject [users@httpd] Handle Multi-Domain Traffic
Date Wed, 22 Aug 2012 16:27:02 GMT
Hello all,

I am having a performance issue with Apache server; I hope you could
provide some hints and/or advices the proper way to implement the
I need to set up a webserver that acts like the Internet to our
testing environment.  All HTTP requests for various domains would be
end up hitting this single webserver for the purpose of performance
testing a proxy server.
The apache server is configured to bind to a single IP (Listen with <VirtualHost *:80>.  Everything works fine
functionally, but I found the throughput drops as the number of
domains used in the traffic increases.  If I have only 10 different
domains in the load traffic, the throughput could reach as high as
5000 hits/second; but going to 50 domains would lower the throughput
to 300 hits/second already, and the similar performance is observed
even I use over thousands of different domains in the load.

I have added the extra column for the page-serving time in the access
log and that verified the high latency in the serving time.

Does anyone have any suggestion of how I should configure the Apache
server to handle multi-domain traffic efficiently?

Thanks and appreciated,
