I received a report about a performance regression on a simple workload of receiving a single TCP stream using a be2net NIC. Previously the reporter was able to reach more than 9 Gb/s, but now he sees less than 7 Gb/s.Yeah, we are aware of this, and we had some discussions, but not yet got a fix. Are you running a 64 or 32bit kernel BTW ?
Both my reporter and I are running 64bit kernels. Thanks, Michal
