NFS Slowness from SunOS4.1.3 to Solaris 2.6

NFS Slowness from SunOS4.1.3 to Solaris 2.6

Post by Doug Kro » Tue, 25 Nov 1997 04:00:00



Has anyone experienced slowdown in communicating over NFS from a SunOS
4.1.3 host to a Solaris 2.6 client?  The test we used was to rdist a
50 MB file from an NFS host to a client.  Both were a subnet that is
not on our main network (hence, no network traffic is involved).  Here
are the results:

HOST Machine/OS CLIENT Machine/OS       TIME to rdist

SS 5 / SunOS            SS 5 / SunOS            01:05
SS 5 / SunOS            Ultra / Solaris 2.6     14:38
SS 5/ SunOS             SS 10 / Solaris 2.6     14:40
Ultra / Solaris 2.6     SS 5 / SunOS            00:58
Ultra / Solaris 2.6     SS 10 / Solaris 2.6     00:51
SS 10 / Solaris 2.6     SS 5 / SunOS            01:05
SS 10 / Solaris 2.6     Ultra / Solaris 2.6     00:53

Obviously, something is happening with the copy from SunOS to Solaris.
We turned off the Binary Compatibility on the SS 10 Solaris, thinking
that may be the slowdown, but it didn't help either, as the times
above show.

Does anyone have any ideas?

Thanks in advance

1. Diff. between SunOS4.1.3_U1 and SunOS4.1.3_U1 VB

Hi,
        Do any of you know the difference between SunOs4.1.3_U1 and
SunOs4.1.3_U1 VB?  Sun has the Y2K patches for 4.1.3_U1 VB? Do these
patches work for just 4.1.3_U1?

        Any information is greatly appreciated.
Thanks
