comment Why is TCP accept() performance so bad under Xen?
Someone poked me on Twitter regarding this question. Unfortunately, it seems as this problems persist. I haven't put much research into since last year. Xen MAY have improved during this time, I don't know. The KVM developer also mentioned they were addressing issues like this. Could be worth pursuing. Also, another recommendation I've heard is to try OpenVZ instead of Xen/KVM as it add less or no layering/interception of syscalls.
