[Solved] C programs slow startup

Question

Are you running antivirus software? My guess is that yours insists on heavy scanning of newly created executables before allowing them to run.

Another possibility is that (at least) one directory in the pathname for the executable file (or for some DLL it depends upon) has a very large number of files in it. On some versions of windows, by making directories containing roughly 64k file entries in them, you can make opening files in their subdirectories arbitrarily slow.
