As promised, I tested with a kernel that I know for fact that I have tested heavy IO on previously, and behavior was identically horrid, so it's not something new that snuck in ~recently, my disk just got a _lot_ fuller in the meantime (12k mp3s munch a lot). I also verified that I don't need to use the dirty data restrictions with ext2, all is just peachy using stock settings. Amarok switches songs quickly, and GUI doesn't hang. Behavior is that expected of a heavily loaded IO subsystem, and is 1000% better than ext3 with my very full disk. Journaling is very nice, but I think I'll be much better off without it responsiveness wise. -Mike - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
