Inter-vlan performance will depend on the router you have stuck in the middle of them.
If its just a basic Cisco 2611 you wont get alot of performance, but if you say stick a 7301 (expensive!) in there with gigabit to each LAN you will get alot better performance.
As the old rule goes, you should aim to keep 80% of each users traffic local. Therefore the only traffic that should need to leave each LAN would be internet traffic, and anything else that isnt local to the LAN (for example, a network admin might initiate a Remote Desktop session to one of the accounts computers to fix something up).
Ive drawn up a quick diagram to show you exactly what ive been talking about. Each of the 3 LANs is a logical group, say for example the 3 I mentioned earlier.
