Re: bad NFS/UDP performance

2008-09-29 Thread Claus Guttesen
 it more difficult than I expected.
 for one, the kernel date was missleading, the actual source update is the 
 key, so
 the window of changes is now 28/July to 19/August. I have the diffs, but 
 nothing
 yet seems relevant.

 on the other hand, I tried NFS/TCP, and there things seem ok, ie the 'good' 
 and the 'bad'
 give the same throughput, which seem to point to UDP changes ...

Can you post the network-numbers?

Re: bad NFS/UDP performance

2008-09-26 Thread Claus Guttesen
There seems to be some serious degradation in performance.
 Under 7.0 I get about 90 MB/s (on write), while, on the same machine
 under 7.1 it drops to 20!
 Any ideas?

Can you compare performanc with tcp?
