Command line EXE is slow, fast in Visual C++ environment

[spidey]

Something weird is happening here... when I run my code from the Visual
C++ environment it is 3 to 4x faster than running the same code from
the DOS command line. Any explanation why is this happening?

Is the executable the same or do you run the Debug version in Visual
Studio and outside the Release one?

T.M.

Actually, it is slower when I use command line.
And yes, I'm using the release version in both cases (I have to move it
from the release\ directory before running it).

How do you know it's slow? Did you add statements to log the times between
critical events? Or does it just "look slow"?

Maybe it's slow because the copy in the Release folder was still in the OS
file cache at run time, so running the program from a different folder
required more disk activity. Either way, the run-time speed should be the
same.
