What does it say within the square brackets in the mode-line of the GUD
buffer _before_ you type `C-c C-c'?  If it says "initializing..." then it
might help to wait a bit longer until it says "ready" before typing the first
command.

There are several factors that might make this slow:

1) An executable that was created from a large number of files.
2) Using stabs debug format.
3) Using an old PC.

If this is the problem I can post a patch that might speed things up but
just turning off gud-tooltip-mode might help.

If you still get an error after waiting for "ready":

1) Set gdb-enable-debug to t using M-x set-variable.
2) Do M-x gdb and enter "run" in the GUD buffer to get the error.
4) Post the value of gdb-debug-log (you can use `C-h v') to the list
  (or just to me if it's large).
