I''ve got Gentoo Linux running as both DOM0 and DOMU on a few Xen boxes, but the NFS client with this configuration is really slow because it keeps timeing out. The following is true: Gentoo (No Xen) = FAST SuSE (No Xen) = FAST Gentoo (DOM0) = SLOW Gentoo (DOMU) = SLOW (Gentoo is DOM0) SuSE (DOMU) = FAST (Gentoo is DOM0) I''ve tried all configurations with both a Gentoo and SuSE NFS server (No XEN) with the same results. I can speed things up by setting rsize and wsize to 16384, but it''s still much slower than SuSE DOMU or non-xen (Gentoo or SuSE). Gentoo (No Xen): 231.7 MB/s (95 MB file) SuSE DOMU (Gentoo DOM0): 339 MB/s (95 MB file) Gentoo DOM0: .035 MB/s (1MB file, rsize/wsize=16384) What''s more, I get slower speeds on SuSE DOMU when Gentoo DOM0 is accessing NFS, so I''m guessing it''s generating network traffic to slow stuff down. And the answers to the obvious questions... - I can duplicate the problem on two differen Gentoo/Xen boxes (one is pentium$, the other is AMD64). - Other other network operations work about the same on various configurations, though SCP only gives me about 10MB/s on SuSE or Gentoo uner Xen while it gives me about 22MB/s on Gentoo without Xen. - I''m using bridging to share the network connection. - I get "nfs: server <my-nfs-server> not responding, timed out" in dmesg in Gentoo under Xen, but not on SuSE/Xen or Gentoo/No Xen. Any ideas why nfs is timeing out under xen and/or how to fix it?
