You are not really one of the few. A lot of my own work is done on a single core pentium M 1.7Ghz laptop. I am not endowed with truckloads of hardware like all the paid developers are. I recall extreme frustration myself when a developer a few years ago (around 2002) said he couldn't reproduce poor behaviour on his 4GB ram 4 x Xeon machine. Even today if I add up every machine I have in my house and work at my disposal it doesn't amount to that many cpus and that much ram. -- -ck - 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/
