Will try, but it is changing to 2200 MHz while I am doing the CPU-intensive tasks (compilation of something big) and the debug printf's are telling about 2200 MHz as well. Not so good benchmark, but at least something. > Also, make sure you're not using the TSC timecounter. sysctl > kern.timecounter I am just using the defaults for the -CURRENT. Can not verify them now -- my -CURRENT is crashing with the modem link, so I am either writing mails or doing the tests, sorry. > >>> First two logs, ifstat.bw3Kb.old.wan.log and ifstat.bw3Kb.new.wan.log > >>> do show the WAN results.

Monday will reveal the things. Will post an update. Thank you! -- Eygene
