No, IMHO simply not optimized enough for program starting. It is no different on a clean windows, and it has always been. The old Unix programmers rule: Windows slow process, fast thread, (free) Unix fast process, slow thread. However this has been changed with NPTL.

I used to testdrive new NT servers at work by doing a FPC build cycle, systems with quite some I/O bandwidth, but they hardly could get by a normal system running Linux. (FreeBSD 3.x wasn't that fast with I/O, that only got in the same magnitude in 4.x times)

So disk caching probably also. In the old days when performance still mattered, building on a scratch partition with "noatime" set could also do wonders.

I recently actually found a registry key on Windows that did the same for NTFS, but only globally. Unfortunately not per filesystem as on Unix.
