There is an interesting doc here:
http://www.cisco.com/en/US/products/hw/switches/ps646/products_tech_note09186a0080094bc6.shtml
We have been using 10 routed interfaces on a 3550 for many months without any
problems. But this 3550 doesn't have a lot of
traffic. We had another 3550 with 8 routed interfaces, which was having issues
with its large routing table (cpu was getting high
& low according to traffic patterns), so we had to decrease its size. After
that, everything is fine.
