Alpha DP264 (UP), SCSI, floppy
If I do a dd if=/dev/zero of=/tmp/moo count=100000, I don't see any increase in buffers, as reported by vmstat. Furthermore, if I read from /dev/fd0, it used to buffer the whole thing, so a second read would be fast -- now it hits the floppy again.
I ran some fairly large things when I first booted, and swapped some stuff out -- I don't know if this would've happened before. But now my buffers number is way small:
procs memory swap io system cpu r b w swpd free buff cache si so bi bo in ... 2 0 0 4568 444984 38008 141744 0 0 4 10 9 ...
and it won't grow much bigger than that no matter what I do.
What's up with buffers?
Confused,
