Luigi one question. Does netmap requires a processor with 64 bits? I'm having some trouble in compiling netmap, using the same Makefile I used previously, but for an Intel IXP435 CPU (Gateworks Cambria). On 28 June 2014 14:07, Carlos Ferreira carlosmf...@gmail.com wrote: Hello to all.

tuning routing using cxgbe and T580-CR cards?

2014-07-11 Thread John Jasem
In testing two Chelsio T580-CR dual port cards with FreeBSD 10-STABLE, I've been able to use a collection of clients to generate approximately 1.5-1.6 million TCP packets per second sustained, and routinely hit 10GB/s, both measured by netstat -d -b -w1 -W (I usually use -h for the quick read,

Marcelo; I recently had a case where an Intel card was flapping, but using LR transceivers. Turns out, the cable ends needed to be re-polished, as not enough light was making it through to register transmit power. You and the networking people may want to spend a few moments exploring that path.
