I recently moved from stable to current (may 1 snapshot) and have begun to ponder bounce buffers, since I have a 32 megabytes of ram in an ISA system and an Adaptec 1542C SCSI controller. Unfortunately I don't have any benchmarks from 2.1, but under current the my system feels a lot slower than before the upgrade. When paging starts, things really slow to a crawl down to a crawl. I'm wondering if any kernel/vm wizards would be able to speculate on whether or not bounce buffer performance may have been a casualty of general vm system changes. -john == jfieber@indiana.edu =========================================== == http://fallout.campusview.indiana.edu/~jfieber ================
