I've included my dmesg and service -e output. ..and now my p7 dmesg as well as the p4 one, and a diff between the two, which highlights two, peculiarities, as Matthew called them: -FreeBSD 10.3-RELEASE-p4 #0: Sat May 28 12:23:44 UTC 2016 +FreeBSD 10.3-RELEASE-p7 #0: Thu Aug 11 18:38:15 UTC 2016 (...) -CPU: Intel(R) Core(TM) i7-4790K CPU @ 4.00GHz (4000.07-MHz K8-class CPU) +CPU: Intel(R) Core(TM) i7-4790K CPU @ 4.00GHz (4439.49-MHz K8-class CPU) (...) -Timecounter "TSC-low" frequency 2000036900 Hz quality 1000 +Timecounter "TSC-low" frequency 1109872466 Hz quality 1000 Not sure which I like better for the culprit, the 4439.49 MHz equals 4.0 Ghz or the different timecounter frequencies. The former nicely corresponds with the "10%" of time I lose. Regards, -Martin
