Dear people, another not-quite-laptop-related-but-only-happens-here story:
After I switched to ext3 on my installation partition (Acer TM 803, Debian stable/testing, based on Knoppix 3.2, heavily upgraded) I noticed a severe performance loss. Actually, the system suddenly felt quite sluggish (especially during start-up). I did some hdparm -t runs and discoverd that the transfer rate had dropped to around 12.9 MB/s from around 20 MB/s. That is a 30 % drop! I cross-checked with my desktop installation (basically the same setup, but of course very different hardware) and I only noticed (if at all) a drop in transfer rate of about 1 or 2 percent between ext3 and ext2. Also, the vfat partition on the laptop delivers the good old 20 MB/s as did the ext2 partition. On the desktop there is also only a small difference between vfat and ext3. Any ideas why this happened? And yes, I have enabled DMA and manually switched to UDMA 5 on all concerned drives. Should I go back to ext2?
