Hello,
I have a box with 512MB of RAM, which is running a snapshot from 2006-02-13.
The box does not get used much, so most of the RAM stays still, i.e.
not used by the userland.
I am now quite surprised why OpenBSD does not use all of this RAM for
disc cache etc.
After rebooting the system, I took some measurements from the root
console (where only one other user was logged in, who ran a `top`
every once in a while).
In the fragment of my session below, you can see that running
identical `find /usr/src/sys/ -name "*.[ch]" | xargs grep qwertyuiop`
command does not seem to utilise any disc cache before the kernel
option gets modified. After we increase kern.maxvnodes by a factor of
16, we immediately get huge benefits of running identical 'find ..
grep ..' command the second time etc.
Before tweaking kern.maxvnodes:
free memory after 'find .. grep ..' is around 368MB
repeated 'find .. grep ..' always take as much as 14 seconds
After tweaking kern.maxvnodes:
free memory after 'find .. grep ..' is around 338MB
repeated 'find .. grep ..' take as little as 3,9 seconds
My question is thus:
Is there a reason no algorithm is used to automatically modify kernel
variables such as kern.maxvnodes to efficiently account free memory
for disc cache?
Here is the session log:
