Hi: uhf used to be running 2.2.2-RELEASE with just wd0 and wd1. It was only a 486/120 with 48MB of RAM and 32MB of swap. It was rather slow and at times ran out of swap. Over the past weekend, I added a 6.4 GB Fireball IDE as wd2 and upgraded to 3.0-SNAP-970807. Unfortunately the Acer AP43 motherboard doesn't handle >2GB partitions, so I made 4 slices. Current config: Filesystem 1K-blocks Used Avail Capacity Mounted on /dev/wd0a 21799 11789 8267 59% /dev/wd0s1e 977351 163191 735972 18% /dev/wd1a 200823 194068 -9310 105% /dev/wd2a 31743 13470 15734 46% /dev/wd2s1e 1905354 129452 1623474 7% /dev/wd2s2c 2034474 334673 1537044 18% /dev/wd2s3c 2034474 29481 1842236 2% /dev/wd2s4c 5622 1061 4112 21% procfs 4 4 0 100% /proc I also added 96 MB of swap on wd2 (128MB total). However, as it turns out, 3.0 seems to have a much smaller memory footprint, and it swaps a lot less (the most swap usage I have seen so far is about 2-5 MB). Which snap are you running? Which program sits in biowait?
