Description Enji Cooper freebsd_committer freebsd_triage 2011-12-22 11:00:25 UTC 
- Some of the defaults in tuning(7) haven't been updated following the changes made to the networking stack and UFS in 9.x .
- The manpage still references sysinstall.
- The manpage is lacking a suggestion to increase kern.ipc.nmbclusters, and in fact the recommended defaults are way too low for cxgb(4), igb(4), and a handful of other network cards (the default today on 8.x/9.x is 25600).

The attached patch improves upon those items.

Fix: Patch attached with submission follows:

       I just reread the proposed addition to kern.ipc.nmbclusters and
cringed at my grammar. The proposed change isn't fantastic either
(still draft quality in my mind), but it's better than the first
proposed change.
Thanks,

    I let some of my tweaks leak into the suggested changes: in
reality, net.inet.tcp.{recv,send}space haven't changed to those new
defaults. tuning(7) is being updated per
http://wiki.freebsd.org/SystemTuning , so I'd just close this PR
because the actual formulated recommended defaults will be determined
there and seriously reviewed, compared to what I did here.
Thanks!
