show sdm prefer should give you hint how many routes
you can push to hardware.

for hardware platform like 3550 this is irrelevant, unless 
you consider convergence speed relevant. It doesn't
slow down packet forwarding at all. But surely
the slower the CPU the slower the convergence, but
I think with parameters given, this is largely 
academic issue to you.
