Kernel memory footprint and analysis.

I am trying to analyze the footprint of my Linux kernel but don't know how each feature breaks down. Is there a tool I can use that will break down the memory footprint of the running kernel? I also want to see what features are being used or not used by the running system in real time. This will help me trim down the kernel and get a better idea of the feature usage.

Look at /proc/meminfo for a general overview and /proc/slabinfo will give information from the kernel slab allocator about the memory usage of various buffers and caches. Beyond that you may wish to look at/tweak some of the vm sysctl variables.
