By the way, Jason. I checked that information:
[root@sandbox src]# sysctl -a | grep buf
vm.buffermem = 2 10 60
Then, I took a look at the "/usr/src/linux/Documentation/sysctl/vm.txt"
file trying to figure out how to interpret those three figures and here is
what I found:
The values are:
min_percent -- this is the minimum percentage of memory
that should be spent on buffer memory
borrow_percent -- UNUSED
max_percent -- UNUSED
This is in a 2.2.15 kernel, so perhaps the documentation changed in newer
versions. So, my obvious question is: are those two other parameters
usable now? The one we seem to be interested on here is max_percent, I
suppose.
