A couple of things to try:
1) Disable the onboard flash and go into a well lit area - allow the lens to auto-focus and fire of a bunch of shots to prove the camera's shot-to-shot cycle time and your memory card is up to scratch. With a fast card, you should be able to get at least 10-20 frames before you notice a slowdown; with a slow one, it might be 5'ish (note these are for RAW's; JPG's could be near double these figures).
2) Full manual mode *might* help here as it does not need to compute the exposure, and thus may not need to fire the flash (Note: I've not actually tried this technique, but it sounds plausible).
If the first one test works fine, it's just the flash (especially if you switch to manual focus) and should be able to be resolved with a faster-cycling external unit. If the first one shows an unacceptable slowing of shot-to-shot cycle times, run some raw file copy tests to and from the card to ensure it is as fast as you think it is (I have an OEM, and thus unmarked/unbranded "160x" CF card for my camera; raw speed tests show it's somewhere between a half and a quarter of the speed of my Sandisk Ultra II).
Good luck!

OK, thanks for the note, RR. That's a major change in the way EOS cameras work over the last 10 years! Darn accountants and their cost optimisation(cutting).
I'm still just looking at digital cameras, so far. The EOS 400D was a lend for the day.
So optimising the purchase for Auto focus, Memory and Flash cycle speeds is still all future tense.
