Im getting a lot of lag when NFS is accessed. The machines having this
problem are all identical hardware. They are being served home
directories via NFS. The problem does not seem to exist in 3.1-RELEASE.
My initial build/install of 3.1-STABLE (3/15/99) did not have this
problem. I upgraded an identical 3.1-RELEASE machine to stable and it
also is having this problem. I see some changes have been committed.
These machines work fine with -RELEASE, and we have an SMP machine
running the lastest -STABLE without problems.
Here I grab a file via ftp, downloading it to a local FS.
27533787 bytes received in 134.06 seconds (200.57 KB/s)
Here is the results of the same file to an NFS mounted home directory.
