Re: [CentOS] kbcached tuning on CentOS 4

Regarding performance, this isn't much of a concern, although this host is intermittently hit with large work loads (which is why the kernel cache reaches the point of consuming all memory) which consume much memory, and another thought was that when these sporadic work loads proceed, there would be a slight performance hit waiting for free memory to be available as the cache is cleared.

If this thought is misguided please let me know. Either way, what would be the correct method for tuning the kernel parameters?

The Linux kernel provides very little parameters for the vm. For what it is worth, go read /usr/share/doc/kernel-doc-2.6.9/Documentation/sysctl/vm.txt

You will get this file after installing the kernel-doc package.
