472.0. "nfs decreased system performance" by DAIVC::RAMADONI () Sat Feb 15 1997 06:11

Dear all,

I have a problem with System performance while the SAP Application activated
using AS 4100 Rackmount (2 units)
The configuration of the system :

- AlphaServer 8400 as a SAP Database Server that connected to SW800.
- AlphaServer 4100 Rackmount as a SAP Application Server that mounted several
  file system from Database Server using NFS.
- Operating System D-UNIX 3.2G
- Firmware Revision 3.8 for both Machine
- 2 DE500-AA installed at 4100 and it set as 10MB.

When all machine up, there was no problem with the performance of AS4100.
But after my customer activated the SAP Application, the performance of 
system become slowed. I tried to checked it using netstat, and the information
of network collusion was very high.

This problem accoured while application activated. But it become normally when
deactivated application.

Does anybody has nearly the same problem ..?
Please reply ASAP..
