> 1. Move your file system in to memory. ( Big bennifits.)
A potentially useful approach, but remember that most file systems contain
a modest amount of heavily-used stuff and a lot of seldom-used stuff. It
may be better to use that memory for a big, intelligently-managed buffer
cache, which will give 90% of the speedup while using 10% of the memory.
(Or, alternatively, will give 90% of the speedup for a filesystem ten times
as large, using the same amount of memory.)
> 7. Recursion anyone? How about recursive compilers, hmm makes me wonder.
The PDP11 cc, running in a distinctly small address space, is a recursive
design.
