Re: Forcing buffer cache to use available memory

2007-10-01 Thread Wojciech Puchar

Hello,

Is there a way to force the buffer cache to be more aggressive when
caching reads? Or even just plain force a certain number of megabytes
to be dedicated to the buffer cache?


it is. sometimes too aggressive.

You want to adjust the vfs.read_max sysctl, I believe, or the vfs.maxbufspace 
for your second question.  sysctl -d vfs is likely to be informative
