Using more memory for disk cache and less for storing rarely used pages sounds 
like a performance optimisation.

Anyway I don't think that there's going to be much interest in performance-
tuning of Lenny kernels now that Squeeze is released.

If you want help in tuning Lenny then probably debian-user or your local LUG
