Hi!

Is there any way to increase the filesystem cache size in FreeBSD
4.3-STABLE? My cache size never increases to more than 69 MB, although
more than 400 MB are free and could (and should) be used for that.

I've seen that "sysctl -a" shows some vfs.* settings that obviously
control the cache size, but I cannot find a way to change those sizes,
because they are read-only.

Can I increase the maximum size at run-time or do I have to specify
that at kernel compile time? How can I do either of that?


Greetings,
Thomas.
