[netdrivers] latest on gige cards and performance?
Wed Aug 27 15:00:04 2003
I'm in the process of planning a gigE network and I'd like to get the
latest on performance tuning for gigE copper and what cards to look at for
maximum performance. If there is a gigE FAQ, please point me to it.
Right now what I have available to play with is a Cisco 6509 with a 48port
10/100/1000 copper blade and a few e1000's. I'd like to benchmark the
different speeds I'm getting while playing with MTU's on these machines
but netperf doesn't seem to like it when I set to MTU to 9000. Ttcp seems
to do the same. Our goal is to see somewhere around 500M/s of raw TCP
between our servers and workstations.
Let me know what factors come into play, any benchmark tools that will
deal with larger frames and anything else I'm missing. WHen I gather info
from the experts on the list I'll write up an FAQ since gigE networks
seems to be a fairly popular thing these days.
