Gmail is push, not poll...isn't it?It's not supposed to be constantly polling for new email. How long are you talking about here. Mine syncs about every five minutes or so. Which is too much for me as it is but there's no way to change that.
If you go into settings, tap the Google act from the menu and it will tell you when it synced last. If it's doing it constantly you're going to have battery issues. Also a weak signal could be causing delays
