Most people have directors with several identical backends. I've got it the other way around: Several standalone apache, lighty and nginx bokses serving different stuff according to host and url.
This particular varnishbox is a HP Proliant BL460c G1 2XDualcore 2.66 Ghz with 6 GB of RAM. Running Centos5.3. Only tuning is /var/lib/varnish on tmpfs The most active backend is a vmware-image running apache and 2GB of RAM. ServerLimit 256 MaxClients 256 MaxRequestsPerChild 4000 Serving approx 25-50 hits/sec On Wed, May 26, 2010 at 11:22 AM, Angie T.
