Hello all, there seems to be a significant performance loss when moving from Madwifi to ath5k. For an embedded project we have been using Madwifi with Linux kernel 2.6.23. We have tested ath5k for some time and by now it seems to be stable enough for production use. Unfortunately it doesn't match Madwifi's performance. Running iperf (both, UDP and TCP) between two machines equipped with an AR5413 with the Fedora 15 kernel and the stock Fedora 15 wireless subsystem shows a performance loss of about 10% relative to 2.6.23 and Madwifi-0.9.4. The tests where done under close to ideal lab conditions (cards connected with an antenna cable) running an IBSS network on channel 40 (5200MHz). Can anybody confirm this observation? Is there an explanation? Are there some tuning knobs I could try to improve the performance with mac80211/ath5k? Is the problem outside the wireless subsystem (Maybe it's the TCP/IP stack or something Fedora specific)? Thanks in advance.
