We also saw some problems with recent Dell machines with “SpeedStep” or whatever Intel calls their power/speed management these days. One developer measured a very significant increase in speed after completely disabling support for it in his kernel on multiple Linux variants. I don’t have the details from him, but he said the system went from “almost unusable on a daily basis”, to, “I can actually get things done”. He mainly uses it as a desktop replacement, so he didn’t care about any benefits from power management to save battery, etc. Very “informal” note… I don’t have the data to turn in bug reports, or time to chase it down. He shared what he did informally with a couple of other devs and “hallway discussions” have indicated that they also agreed that they had better performance from the machines. -- Nate Duehr denverpilot at me.com > On Jun 19, 2015, at 13:57, johan.vermeulen7 at telenet.be wrote: > > > > ----- Oorspronkelijk bericht ----- > Van: "Nicolas Thierry-Mieg" <Nicolas.Thierry-Mieg at imag.fr> > Aan: "CentOS mailing list" <centos at centos.org> > Verzonden: Woensdag 17 juni 2015 14:46:37 > Onderwerp: Re: [CentOS] CentOS 7 + Dell Latitude E6420 laptop = thermalshutdown > > On 06/17/2015 04:49 AM, deoren wrote: >> >> I'm still puzzled why the laptop appears to lockup when attempting to >> login to the desktop environment when using CentOS, but not Ubuntu >> 15.04.
