I have moved jenkins master from win7-64 to ubuntu 12.04 and it didn't change the situation. Once the load increases, reload of the main dashboard produces a couple of 304s (Not Changed) with response time over 5 seconds.
However, once jenkins is deployed with tomcat problem is gone. The response time for static content went down. On the same network segment all 304 complete under 20ms. The following is used as a load test: 4 machines, each running: while /bin/true; do time wget -q -E -H -k -K -p -e robots=off http://whatever/jenkins; done + browser pointing to front page with auto reload enabled. cheers pawel On Sun, Jan 20, 2013 at 12:06 PM, Yitzhak Zuriel <zurie...@gmail.com> wrote: > We also use the winstone http server that comes out of the box with > Jenkins.
