It's not always the case. On modern CPU, its large cache helps a lot
(e.g. the whole compression and decompression code might fit in the
instruction cache). Not too mention that compression actually makes
you allocate/access/use *less* memory. I predict that it is just a
matter of time that the improved multicore CPU performance causes the
compression overhead to be negligible compared to memory access time.

To make it short: the best way is to try it :-)
