You don't mention it, so I have to ask: are you saying that Windows clients on the same vlan have normal/fast file transfers?
Are all hosts/links/trunks gigabit ethernet?
Is the Mac server providing DHCP and DNS?

hi schaps... client are using dhcp, pointing ad dns as promary dns. there is no complaint file transfer from windows to windows server... only happen mac client to mac server..... all are gig network.
server and clients are different vlan
It could be a problem of spanning tree settings on your switch. It should be turned off if you really don't need it.

i do not have problem with windows users on windows server.... in fact... i dont think i got spanning tree.... is all just chained...
the spanning tree settings affects AFP protocol only, you can't experience the same problem on Windows. Alternatively try to connect to server via SMB instead of AFP.
