It definately isn't helping. > OK, one problem is most likely something I added a month or so ago: a new process is now assumed to be not a good anticipate candidate. This solved some guy's obscure problem, but a lot of programs that benefit from anticipation (ls, gcc, vi startup, cat, etc) are only going to submit a few requests in their life, so they lose most of the gains. I have some automatic thingy I'm testing at the moment. The other problem could well be a big TCQ depth. AS helps with this, but it can't do a really good job. Try a TCQ depth of max 4. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ | ||||||||||||
