Depending upon how much memory you have, it might have a large
effect. Increases in memory use increase the amount of paging your
program will do. If the paging is from main memory to CPU cache, that's
not too bad; it if it's from disk to memory, that's bad. (These are
two different senses of "paging".)
The effects may be felt in the program with the increased memory
footprint, or in other programs if they end up doing more disk paging.
It's possible the system if pretty clever about this (e.g., the
symbols just stay on disk until they're needed). If so, the effect
would be negligible; I don't think the system is that clever.
