Cisco WS-C2912MF-XL

[Zelandakh]

Got one of the above fibre switches. It has 2924s off it in a star formation so this is the central switch and everything goes through it. Two 4 port Cat5 modules plugged in its expansion ports. These host my servers. As this is the main switch, I'd like to make it run smoother / faster. Is there anything I can do? I believe I need to turn spanning tree off because I use macintoshes (can someone confirm?).

Servers and applications I can do - switches I can't...
