I tried the KOTD kernel today (2.6.31.7-0.0.0.8.a22d080-desktop).
While *reading* a large .iso file (over NFS!), dd reported 86.1 MB/s.
That is really fantastic.
I mean really really awesome. Previously, I would average 1/3 of that.
Smaller files still hurt pretty bad, and my average (reading from raid6) is
still only 45-50MB/s, but that's pretty reasonable I think.
And what's more I didn't get any rpciod issues.
Reading from one NFS share and writing to another results in /reaaaaaly/ bad
NFS performance: iptraf reports highly variable flow rates, typically below
2MB/s with occasional short burts to 5MB/s. When reading I'm able to achieve
much more than that (see above). However, rpciod no longer consuming 100% CPU
and hanging the box.
If it goes funky again I'll report here.
At this rate it will be many hours before it is done copying.
