That was on 2.4.21-pre or even patched 2.4.20 (on siimage - in it's early stages, not sata_sil driver). Now it's 3 times slower (checkedwith preemptible kernel, it's even slower) - so something went bad. -- Witold Kręcicki (adasi) adasi [at] culm.net GPG key: 7AE20871 http://www.culm.net - 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/
