I am don't subscribe to freebsd-net. I am quick look into thread and don't see this information. For you case collet also `top -PHS` and may be you need capture nfs seession by tcpdump and analize this by wireshark (may be solaris servered synchronus write). > I just wanted to let /you/ know that my interrupt rates look similar (you > asked for that). My case is very special -- I am realy have 3Mpps syn-flood and try to mitigate this by netmap filtering. > I think there are a couple of people on the mailing lists reporting > performance issues with ix interfaces and (especially?) NFS lately. Would > be great if we could find and fix the root cause(s)... Nobody do instrumental analysis. I see only guesting. My experience talk: before solve software problem make sure no hardware problem. For this need to collect `show interface`, netstat and etc. My experience talk: before tuning make sure what tuning need and so. For this need capturing nfs session and analise by wireshark. May be just solaris on every write do sync. _______________________________________________ freebsd-stable@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org"
