I also ran: hdparm -tT /dev/hda, as described in the windows thread by Karsten, and it came in at 28 MB/s Decent, not great. - Does the processor speed have anything to do with I/O performance? Not directly. Processor speed on blocking tasks (encryption, find/sort, compression, decompression

Right, 2.4 vs 2.6 kernels handle I/O differently, I don't consider dd a very good measurement of performance since read/writes to raw disk devices (without caches, buffering, ordering, or filesystem) are pretty rare. Oh, so it very well may be an apples to oranges comparison? So Knoppix is config

Hi, I just installed Sarge on an old PPro 180Mhz, with / on a RAID1 device and everything else on RAID1/VG/LVGs (which is very easy using the new Debian installer). I'm building this machine to be an offsite backup machine. It took 10hrs to sync my 100GiB partition, the first time, which seems
