Ours are all virtual here. The "noisy" ones can maintain ~150-250Mbit during media crunches with hardly any load at all, although they typically hover at 20Mbit or less since they are Akamai origin servers. Internal load testing has run them up to about 4.0-4.6 Gbit serving 100% cached content. VMWare ESX and EMC back end, 10G networking. VM's are 2 vCPU and 16GB RAM, RHEL 6.4.

Hi, Don't bet too much on seeing high performance caching in virtualized infrastructure. The disk I/O performance required for caching and storing is too high, so using virtualization will decrease the performance due to random I/O operations from different VMs. good luck!

With 150mbit internet line and thousands (more than 10k) of students, i really hope ATS + cacheurl would saves our bandwidth. My question, can youtube be cached ? Because my regex that i ask couple month back did not succeed. Have anybody got any success caching the youtube video ? If yes, can it be shared ? Secondly, i'm also doing my masters degree & my project would be proxy efficiency namely ATS & squid operating on baremetal server and also on virtualization with Xen, KVM & VMware ESXi in mind. I hope i could seek help and advise from all the gurus and sifoos here. Thanks.
