next in thread | raw e-mail | index | archive | help
I'm running FreeBSD 5.0-RELEASE on a dual P3 800MHz/512MB/Tekram DC-390
SCSI. Moved all my IDE disks on another 'puter to access via NFS. So I
ended up putting up a Debian server, because some of the disks were
already in ext2fs. Now I'm experiencing heavy lag on my desktop when I
use the NFS intensively, like copy a large file over. I get these 1-3
second pauses in everything, looks like ssh lag but it's local(!). Mouse
pointer in X doesn't seem affected, but even console lags if you type
in.
I'm using NFSv3, tried it over TCP too, but since it's LAN, i dropped
back to UDP.
Here's dmesg:
cam: using minimum scsi_delay (100ms)
