Speed comparison

is somewhere available a comparison between different 10/100/1000 manageable switches showing each packet per second throughput?
or recommendations of some used in low budged computer clustering?
Note that any comparison you find will be subjective. It all depends on what type of packets are being processed. I would lean towards the better gear like Cisco. You might see what you can pickup off of ebay or something like that to help keep the price down.
