I can understand that.
However, just for information, I'm currently working on a rather large piece
of software which loads around 200 DLLs on startup (that's 80MB loaded from
disk). The first, cold start can actually be a bit long, around 10s-15s on
currently medium hardware. The second and next ones are way faster, thanks to
system's cache, around 2s-4s - counting all the other actions we're performing
aside from just loading DLLs. This behaviour has been observed since WinXP
(maybe Win2k, not sure), I guess it would be similar on Linux and others.
Anyway, I guess it's only one more sign of the whole world moving to 64bits ;-)
