There are two things to bear in mind: Shutter delay ie the delay between when you press the button and when the image is recorded. This can be painfully slow on some compacts.
Secondly the time it takes to write the images to the memory card. Some compacts offer a buffer of for example 5 frames per second for a second, but then take a minute or so to write those images from the buffer to the card. During this time your camera is will not work.
I guess that this is down to product placement in the market place. If you pay £4,000 for a professional slr you will expect it to shoot continously at 8 frames per second and write the images in real time. At the other end of the food chain if pay £300 for a compact you can't expect the same performance.
