Description of problem:
NFS is very slow with SCSI drives when writing small files. I have a system
with both IDE and SCSI, if testing locally, SCSI is faster than IDE drive. But
NFS on SCSI drive is 200%-300% slower than NFS share on IDE drive. I have
tested on other systems with RedHat8, and experience the same problem, NFS is
much slower on SCSI especially when writing lots of small files an the shared
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1.Create NFS share on SCSI drive
2.Mount the share on a system
3.running copy directory which contains many small files to the NFS shared
4.Do the same for an IDE drive to compare the result.
I see a similar problem with files of any size..
I created a 100MB file on a RH 7.1 system and RH 9.0 systems.
When I mount the file systems on a Solaris 8 system, the 7.1 copies
the file in about 15 seconds, while 9.0 is still going after 5 minutes.
/etc/exports entries are identical.
solaris mount commands are identical.
We think this was do to some major VM issues. Please upgrade
to a later to kernel.
