Subject: NFS speed problem when appending data to existing files
Date: Wed, 8 Oct 2003 17:53:45 +0200	[thread overview]
Message-ID: <20031008155345.GA15071@vwisb7.vkw.tu-dresden.de> (raw)

Hello,

the following command

for i in `seq 1 10240`; do dd if=/dev/zero bs=100 count=1 2> /dev/null | tee -a tmp0; done

is very slow on a nfs mounted homedir and I get lots of error messages

nfs: server xxxxxx not responding, still trying
nfs: server xxxxxx OK

on the client side (2.4.22, server is a 2.4.21 kernel based nfsd). Only
appending small amounts of data to an existing file shows the problem.
Writing a large file happens at FastEthernet speed flawlessly. Any help,
please?

Thanks,
Torsten
