I skimmed over the archives and didn't find a mention of this. I thought I'd noticed this when I first installed 2217, but I was too busy to verify it at the time.
Simple case: Under 2216, I can do a 'badblocks /dev/hda1 XXXXX'. Vmstat shows about 10,000K/s average. This is consistent with 'dd' operations I use to copy partitions for disk mirroring/backup.
Under 2217, the xfer speed drops to near 1,000K/s. This is for both 'badblocks' and a 'dd' if=/dev/hda of=/dev/hdb bs=256k. In both instances, I notice a near 90% performance degredation.
Haven't tried any latest 2.2.18's -- has there been any work that might have fixed this problem in 2218. Am I the only person who noticed this? I.e. -- maybe it's something peculiar to my HW (Inspiron 7500), IBM DARA-22.5G HD.
