After working with VB6 and "classic" ASP for so long, I got spoiled with effectively nonexistent compile times. Part of that, of course, is due to how old the environments are-- or were. I remember using VB5 shortly after its release on Pentium 1 class hardware, and it wasn't what I would call 'fast' either.
That’s northwood, prescott, and extreme edition respectively. The prescott has other enhancements (and problems, like longer pipeline and higher latency) so the 1024kb step isn’t in line; I’d expect a true northwood with 1024kb L2 to do a bit better.
Looks like the Prescott isn’t much of an “upgrade” for compile time, anyway.
