[c-nsp] Cisco Routers: Performance benchmark

[bored to death]

hi,

for my research, i was looking for some documents about performance 
specifications and benchmarks of cisco routers, such as 2800 and 3800 series. 
oddly, i couldn't find any good document about these aspects of routers, on 
cisco website or by searching in google. the benchmark parameters i'm looking 
for, are standard things like maximum throughput, router throughput with 
different frame sizes (64B~1500B), routing protocols throughput and latency 
(throughput of router on ospf, rip, bgp, ... routing protocols), latency, etc.

can anyone help me with this? does anyone know any documents which describes 
cisco routers' performance parameter values? if not, does anyone have any 
suggestions where may i find my answer (what forum, mailing list, ...)?

thank you.
