I'm still guessing that you don't have a very fast machine though - even my slowest (a quad i5 w/16Gb RAM) doesn't even blink on jobs like that. I'm currently compiling firefox nightly on it right now with -j4, all cores hitting 100% frequently while typing this and surfing my daily websites, all with no discernible lag - not to mention bittorrent seeding 25+ files, several SSH sessions open and in a second I'll be kicking off a full disk imaging for a trashed laptop drive. I'm not a patient man, I like to do everything right now. On that note - I don't think this is off-topic, I might need to change the subject title though - my multitasking, machine-battering work methods have been hugely improved by switching to the awesome pf-kernel* image: the BFS**/BFQ kernel and disk schedulers are a revelation, particularly on machines with very heavy disk I/O that live constantly in the 90%+ usage zone (i.e., all of mine). There are packages available for several distros including Ubuntu/Debian/Mint and Arch, Gentoo, etc or you can just do what I do and apply the patch directly to a bare 3.10 kernel source, after making even more modifications to it. I'm really, really happy with it after a couple of months of pretty much exclusive use - you probably won't need it or see any difference unless you're constantly battering your ideally SSD-equipped with RAM cached system with enormous parallel I/O though. ghost@failbot:~$ uname -r 3.10.1-pf Regards * http://pf.natalenko.name/ ** BFS is an acronym for something very funny, which I will not mention here as some list members might be cross with me :] -- The Mailing List for the Devon & Cornwall LUG http://mailman.dclug.org.uk/listinfo/list FAQ: http://www.dcglug.org.uk/listfaq
