Are there any pointers to multicast performance numbers on a cisco switch?

Hi,
It depends on the switch platform, and (if applicable) supervisor revision.
For example, here's the info for a 6500 with a supervisor 2 (up to 170 Mpps):

Thank you.
Actually, i am looking spec on 2950 /3500/4000 switches.

Hi,
For Layer 2 platforms, IGMP snooping is implemented in hardware, so forwarding performance is only limited by the overall performance of the switch. Unconstrained multicast are forwarded as broadcasts, so the same restriction applies.
2950 specs:

Couldn't find any specs for the 3500Xl switches, as they are well past end of sale, but they'll operate the same, with the exception that they use CGMP rather than IGMP snooping.
For the 4000, i'll need to know which supervisor, and if you are talking about layer 2 multicast or multicast routing.
HTH,
Bobby
