From Bugzilla Helper: User-Agent: Mozilla/4.0 (compatible; MSIE 5.5; Windows NT 5.0; T312461; .NET CLR 1.0.3705) 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 directories. Version-Release number of selected component (if applicable): How reproducible: Always 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 directories. 4.Do the same for an IDE drive to compare the result. Additional info:
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.
