depends on the cache size. the default "16 256" is usually enough

large numbers usually degrade performance (it depends on how the FS proc
esses directories with large numbjer of files).
If you have big cache and many files, you probably should increase L1
(I had to change it to 32 on 18GB disk and 64 on 36GB disk)
if you have small cache, you may decrease L2 but I don't think it will help
you much.
