Hi John,
2.4GHz core 2 duo laptop, pristine boot of 8.0 to check cpu use as reported by conky. No save file, no setup done. With no governor installed, both cpus at 2.4GHz, I see a cpu use for each at idle of 0.5%. With my conservative governor installed and both CPUs at 0.8GHz, the reported cpu use at idle rises to 1%. This is in line with what I see in alphaOS 6.0 with the 3.8.3 kernel and with fatdog64, which uses a 64bit 3.8.7 kernel. That's about as good as it gets on this laptop. For comparison, the linas with 3.2.13 kernel, come in about 5% with governor, Lighthouse64 with the same kernel as fatdog64 !!! at 5% also, Tinted slacko with a 3.2.33 kernel higher at 7% to 8%, and boxpup 412 with a 2.6.25.16 kernel at also on the high end at roughly 8 to 10%.
Sorry I don't replicate your 8.0 numbers. Surprises in my numbers for me were:
That fatdog64 matched alphaOS 6.0, my previous coolest cucumber.
That LH64, same kernel as fatdog64, used much more cpu at idle.
That tinted was as high as it was wrt the linas and pretty much the same as the old 2.6.25.16 kernel boxpup 4.12 with very little cpu finesse. Edit: My guess is that some of this is probably panel related.
All of my laptops at this point are Fujitsu lifebooks with all intel cpus, video, wireless, and glue for what is's worth
All the above numbers are on the same laptop and checked multiple times over a timeframe of weeks with the exception of boxpup, just a quick look.
I have seem fairly high cpu use on both 7.0 and 8.0 after thrashing about in pwireless2 trying this and that to connect. When that occurred, a simple restart of X brought it back to normal.
toastily...or non-toastily,
