I may be wrong, but I'll bet that what you heard was regarding disk caching, and not L2 memory caches. Usually, it's a lot better to let the OS handle caching af disk, because
1) it knows better what you're going to need next from the disk
2) if you don't do much disk access, it can use the memory for other, more useful purposes.

Linux is probably as fast or faster than most competing OSes, but mainly because it has been more thoroughly tested and optimized, and because it has been written by people with somewhat more limited hardware resources than your average big computer corporation.
