faster compiles

[soumik]

Hi All,
I work on a system which has grown to be @8000 files now and VC6 takes
@30 minutes to compile all on my P4 HT machine with a SATA drive.

I noticed that there neither the CPU or the memory (page file) is
being maxed out during the compile so, guessed that the bottleneck is
the hard disk speed. so, I got the fastest SCSI disk that I could
afford (seagate chetah - 4.5 ms seek time 10000 RPM) but there is no
difference in the compile time at all!!

What is going on here? How can I compile faster? BTW, is vc7 faster
than 6?

Thanks.
Soumik.

This is not topical for this group, which covers the C++ langauge only.
Please ask in a group such as microsoft.public.vc.language.
FYI, there is some software that allows fasters compiles by distibuting the
work over various computers on the network. VC7.1 (2003) seems to be a tad
slower, but not much, to me.

And you're complaining? How about several hours to compile? Split
your project into smaller components and only compile the ones you're
working on.

No, it probably isn't. The code it produces is.

Anyway, this is not a LANGUAGE question. Please find a better NG to
ask compiler-specific questions. I recommend anything with
'microsoft.public' in its name, like microsoft.public.vc.ide_general

I don't mean to contradict Victor or Pete, they are probably correct -
the is most likely a question for another group.

But one thing comes to mind. Take read through John Lakos' book (Large
Scale C++ Software Design). There are some rules/hints in there
regarding headers and including files that you can check against your build.
