Hi, I have two server, both runs Xen 3.2.1. Packet rate did not cross 30kpps. Network is onboard S5000XVN/S5000VSA Intel PRO/1000. Does Xen has some packet rate limit? This is bridged setup. On Dom0, netback "eats" 50-60% CPU at 30/30 kpps, speeds are at 13/22 MB/s (in/out). Thank-you. _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Thanks for right point. ebtables was the culprit. Luke S Crawford wrote:> DB <icommitter@gmail.com> writes: > >> Yes.
