           Summary: Sometimes desktop hangs for some time, with an nfs
                    mounted home
           Product: openSUSE 10.2
           Version: Final
          Platform: 32bit
        OS/Version: Linux
            Status: NEW
          Severity: Major
          Priority: P5 - None

Sometimes desktop hangs for some time, with an nfs mounted home this happens
after a upgrade to opensuse-10.2.  Before 10.2 this behaviour was not present,
neither on 10.0 nor 10.1.

Perhaps the problem has to do with those bugs to:
Bug 227645 - NFS has upload limt of 50 KB/s
https://bugzilla.novell.com/show_bug.cgi?id=227
Bug 229848 - unable to access certain web sites
https://bugzilla.novell.com/show_bug.cgi?id=229848

I have not been able to debug/benchmark my nfs setup as described in
bug report 227645:
*Tested diffrent blocksizes (1024, 2048, 4096, 8192, 16384 and 32768) and
benchnmarked them with:
# mount files.first.com:/home /mnt -o rw,wsize=1024
# time dd if=/dev/zero of=/mnt/test bs=16k count=16k
Every benchmark had around the 25 MB/s

If I do that I get:
# time dd if=/dev/zero of=/mnt/test bs=16k count=16k
dd: opening `/mnt/test': Permission denied

real    0m0.003s
user    0m0.000s
sys     0m0.004s

I don't know what is the reason for that.

I have a wireshark dump of 55MB, that shows some interesting output, perhaps
you want to receive this?  Before I attach it to the bugreport, I'll provide
an ascii dump of the headers.  A short dump of output follows below:
> grep "  430[89]." wireshark.out | cut -c65-

On a correct working system, I think that the "RPC Continuation" and
"reassembled PDU" shouldn't be there.  I can't remember I saw those on systems
prior to 10.2.
