NFS-performance drop with 2.4.4 and 8139too
When upgrading from kernel 2.4.3 to 2.4.4 my NFS-performance drops badly. NFS-server: knfsd, linux-2.4.4, 8139too-0.9.16 NFS-client: linux-2.4.4, 8139too-0.9.16 transfers seem to start with about 2 MB/s but drop immediatly to about 20 K/s. http, ssh - performance is as usual. When switching the client back to linux-2.4.3 with 8139too-0.9.15c nfs performs with about 6 MB/s which is fine with me. Please tell me if I can provide any further helpful information.

pdc20267 both channels share one IRQ
Is it ok for an Promise Ultra 100 to have both channels assigned the same IRQ? I have one DTLA-307030 attached as master to each channel and get transfer rates at around 12 - 16 MB/s. As I have heard people reporting transfer rates of about 24 - 28 MB/s I was wondering if there were some connections. Is it me just being dumb and ignoring obvious facts or something misconfigured weirdly with my system? Hendrik I'm subscribed. -- "And I'm right.
