Matthew Wilson has written an article for CUJ which does some performance comparisons for various C++ compilers at http://www.cuj.com/documents/s=8943/cujexp0312wilson/. Of special interest is this chart http://www.cuj.com/documents/s=8943/cujexp0312wilson/wilson_f2.htm.

I've already seen another comparison table about performance (on dm site I think). But I found that with the METAKIT library, digitalmars executable is 3 times slower than VC5 !! search in 50000 records database with vc5 : 24.931111 ms/search search in 50000 records database with dm8.38: 65.156000 ms/search and this is a problem particularly because I use the metakit library for quick searches...

BTW, Matthew, afaik there is nothing like Watcom 12.0 listed in your article. There is Open Watcom 1.0 and 1.1 (1.2 RC for braves). They internally have __WATCOMC__ predefined with value adjusted to mark continuation of development but using it for naming whole product is like calling DMC Symantec C++ just because it has __SC__ predefined. Any chance for such interesting article about strong FPU/double operations? ABX

I'm still stuck in the old Watcom mode. I should start talking about OW 1.0 etc. Please feel free to point it out if I do it again. :)Any chance for such interesting article about strong FPU/double
There is a strong chance, once I'm past the book deadline (2nd Feb). By all means write to me again after that time and remind me Cheers Matthew
