I have a similar problem as Splash posted on May 18, 2006 and Gislain
Hanson posted on May 11, 2006.

Since upgrading to NW 6.5 SP5 & GW 6.5 SP6 the GWTSA module seems to load
OK but ArcServe9 fails to recognise the existence of the GroupWise system.
I have upgraded ArcServe to version 11.1 SP1. Patches and tips from the
forums are installed

The backup is very slow since Arcserve 11.1 SP1 does not use "Performance
Nakoma method" as it did with Arcserve 9. There is a pause for several
hours in the backup.

What can I do to make sure that Arcserve 11.1 Sp1 uses Performance Nakoma
