I was getting a bit more than this in the general case with the last cut of cerowrt.
what are y'all getting with a good (300Mbit) link and various wifi cards? ---------- Forwarded message ---------- From: Ben Greear <[email protected]> Date: Mon, Jun 4, 2012 at 7:29 PM Subject: tcp wifi upload performance and lots of ACKs To: netdev <[email protected]> I'm going some TCP performance testing on wifi -> LAN interface connections. With UDP, we can get around 250Mbps of payload throughput. With TCP, max is about 80Mbps. I think the problem is that there are way too many ACK packets, and bi-directional traffic on wifi interfaces really slows things down. (About 7000 pkts per second in upload direction, 2000 pps download. And the vast majority of the download pkts are 66 byte ACK pkts from what I can tell.) Kernel is 3.3.7+ Anyone know of any tuning parameters that would let the receiving socket wait a bit longer and send more ACK data in fewer packets? Packet traces and other info available if anyone wants to take a look.
