Open Transport on System 7.6.1 is a lot better and faster but it does not work on the older 24bit Dirty ROM machines.
But in thinking - look inside your extensions folder at around the networking extensions. Disable the following if you find them:
Novell extensions/Control Panels, IPX extensions/Control Panels, Token Ring extensions/Control Panels, and NuBus network Extensions. The last one because this is a PDS machine an not a NuBus machine as memory serves me.
Keep: AppleTalk extensions/Control Panels, PDS Network Extensions, MacTCP/IP extensions/Control Panels and a few others.
If Open transport is in the system, keep it unless it crashes on boot (which happens on some machines). Then you need to disable it.
Again, this is by my memory, which is not perfect. But as I remember, doing this on my powerbooks and Mac IIci, it did speed things up.
