X-Accept-Language: hu,en Sender: linux-kernel-owner@vger.kernel.org X-Mailing-List: linux-kernel@vger.kernel.org Content-Length: 1103 Lines: 32 Hello, I have a very simple NFS setup over a siwtched 100Mbit/s network. client is Celeron 400MHz/256M RAM, using XFS server is dual Pentium Pro 200MHz/1G RAM, using XFS server is running Linux 2.4.19-pre8aa3. Network bandwith can be utilized, because ICMP flooding the server results in ~20000 kbit/s network traffic (as of iptraf), but NFS (v3,udp) write performance is unacceptably slow (around 300 KiB/sec), same results with the following kernels: Linux 2.4.18-WOLK3.1 Linux 2.4.18-wolk3.7.1 Linux 2.4.20-pre8aa2 However, with 2.4.19-rmap14b-xfs the very same NFS performance tops out at 2.54 MiB/sec. What's the catch?
