I will not trust the quality of any code which need 10x more resources available than needed to do the job. Even 1Gbps should be attainable with only 128k clusters. - Arnaud > On Mon, Mar 14, 2011 at 4:02 PM, Arnaud Lacombe <lacombar@gmail.com> wrot= e: >> Hi, >> >> On Fri, Mar 11, 2011 at 9:57 AM, =D6zkan KIRIK <ozkan.kirik@gmail.com> w= rote: >>> Hi again, >>> >>> I wanna share state of test machine. em-7.2.2 driver runs as kld.
