We are upgrading from 9.0.1 to 9.1.1. The automatic update process was going very well, and then, for some reason, the transfer rates hit the floor. At the moment this is on our LAN and the transfer rate is probably at 56k speeds at best. Regular file transfers seem to be going at pretty normal speeds.
Acurcl is running on AIX 5.3L, and I tested the transfer speeds on a couple of computers with both Windows XP and 7 and at different points on the network with each getting the same results.
