Environment

Novell NetWare 6.5 Support Pack 6
Novell NetWare 6.5 Support Pack 5

Situation

Slow Backup Performance
TSATest shows slow performance

Resolution

If a server-based antivirus application is configured to scan modified and accessed instead of just modified, it slows file access times way down.
If a file is compressed it has to decompress, scan, then re-compress it, further slowing things down.
The solution is to have the anti-virus application scan just modified, not modified and accessed.

Additional Information

The customer was seeing TSATest results in the 700mb/min range when he had other similar servers that achieved well over 1000mb/min.
