Subject: Microsoft Visual C slower than Gnu C ?

Hi!

I'm about to commit suicide.

I worked hard to port Tiger from Gnu C (free compiler) to Microsoft
Visual C++ 4.0.

Everybody told me: "go on, you're going to get a huge speedup".

Well... What I get is a 10% SLOWDOWN!!! All speed optimizations turned
ON. And the fastest code is achieved when I select 486 instead of
Pentium!

Several possible explanations:
1) I should upgrade to a better version of MSVC...
2) I am calling a fonction that is very time consuming under MSVC, and
is cheap under GnuC...
3) Microsoft wants to see me dead. I'm suspecting something like that
since the first day I installed W95. And crashed my hard disk.

If anybody has stories to tell about porting to this compiler...
Thanks... Maybe you're going to save a sinner's life...
