I don't have benchmarks, but have sites running haproxy on Xen VMs with apache
on Xen VMs and can pump 120 Mbps and 80 million hits a day through one haproxy
VM and that is with haproxy doing rsysloging of all requests to 2 remote
rsyslog servers on top of the serving of requests with some layer 7 acls to
route requests to different backends. Only 50-75 backend servers total though.
http keepalive helped alot with the type of requests that haproxy serves so it
reduced the work load some from the non-keepalive version.
I also use auto-splice on there to reduce overhead somewhat.

Does anyone know of studies done comparing haproxy on dedicated hardware vs
virtual machine? Or perhaps some virtual machine specific considerations?
