Hello,
Looking at my i386 box with 1.5GB of RAM, I see that the "metadata buffer"
use is always 100%:
/0 /1 /2 /3 /4 /5 /6 /7 /8 /9 /10
Load Average >>>>>>>>>>>>>>>>>>
There are 6144 metadata buffers using 78720 kBytes of memory.
There are 213862 pages for cached file data using 855448 kBytes of memory.
There are 978 pages for executables using 3912 kBytes of memory.
File System Bufs used % kB in use % Bufsize kB % Util %
/usr 3560 57 9505 12 45688 58 20
/ 2582 42 19540 24 33004 41 59
/net 1 0 8 0 16 0 50
/home 1 0 8 0 12 0 66
Total: 6144 100 29061 36 78720 100 36
I'm wondering how much this is affecting performance, especially considering
that almost half of the buffers are used on /, while I am currently
running a 'make build' in /usr/src.
Are there any stats available on buffer misses, or the rate of buffers
being recycled?
