Hi Oleg, I don't have any network card errors in the output of ifconfig. The only suspicious thing is the error message from samba, which is included in my original posting.
Unfortunately, I cant't easily test undertake various test series, because this is a production system and we have mostly converted our reiser partitions to ext3 for stability reasons. Now, that you encourage me, I will try to convince the people here to start 2.4.18 and I could have another try with a large file over knfsd. Switching to a 100MBit/s card is even harder, because we have to physically rearrange our network, so no chance for that at the moment... Concerning samba using kernel oplock, I just looked into the samba sources and found, that samba uses fcntl(fd, F_SETLEASE, leasetype) to set locks on files, which they call 'kernel oplocks', so maybe this explains more to you, why samba and knfsd show a similar behaviour. So hopefully I can come up to you with a 2.4.18 benchmark tomorrow. Regards, Wolfgang -- Dr. Wolfgang Glas EV-i Informationstechnologie GmbH.
