Thanks for the suggestions, and I've done some initial adjustments with beneficial results. I was a bit more conservative and went for a 1MB sendbuf_max / recvbuf_max. One thing I didn't see was any corresponding adjustment of kern.sbmax; doesn't it also need to be as large as you want the TCP window to be able to grow? Best regards, - HÃ¥vard
