Everything is fine with my system until the loading gets to the point where it is starting to swap and then it performs appallingly. The paging code sounds like its writing out at a byte at a time to the disk! If I have three active processes at this time then the system starts to thrash:-( The last kernel I compiled was on the 10th of June and did not notice any problems with that. Here is the output from top when the performance is just about to go through the floor. load averages: 1.45, 1.28, 0.94 17:19:09 85 processes: 1 running, 84 sleeping Cpu states: 3.5% user, 0.0% nice, 13.2% system, 2.7% interrupt, 80.6% idle Mem: 19M Active, 22M Inact, 5360K Wired, 264K Cache, 6242K Buf, 96K Free Swap: 102M Total, 4396K Used, 98M Free, 4% Inuse here is the output from dmesg 6450 lpt0 at 0x378-0x37f irq 7 on isa lpt0: Interrupt-driven port lp0: TCP/IP capable interface lpt1 not found at 0xffffffff lpt2 not found at 0xffffffff mse0 not found at 0x23c sio2 at 0x3e8-0x3ef irq 10 on isa sio2: type 16550A sio3 at 0x2e8-0x2ef irq 11 on isa sio3: type 16550A fdc0 at 0x3f0-0x3f7 irq 6 drq 2 on isa fdc0: NEC 765 fd0: 1.44MB 3.5in wdc0 not found at 0x1f0 wdc1 not found at 0x170 bt0 not found at 0x330 uha0 not found at 0x330 aha0 not found at 0x330 aic0 not found at 0x340 nca0 not found at 0x1f88 nca1 not found at 0x350 sea0 not found wt0 not found at 0x300 mcd0: timeout getting status mcd0 not found at 0x300 mcd1: timeout getting status mcd1 not found at 0x340 ie0 not found at 0x360 ep0 not found at 0x300 ix0 not found at 0x300 le0: no board found at 0x300 le0 not found at 0x300 lnc0 not found at 0x280 lnc1 not found at 0x300 ze0 not found at 0x300 zp0 not found at 0x300 npx0 on motherboard npx0: INT 16 interface sb0 at 0x220 irq 5 drq 1 on isa sb0: sbxvi0 at 0x0 drq 5 on isa sbxvo0: sbmidi0 at 0x330 on isa changing root device to sd0a syncing disks... 21 21 20 14 7 done Rebooting...
