After I update my ipad to IOS7, the keyboard did not work normally, It's so slow to type a letter (another touch work normally)

I have the same problem -- keyboard lag. When I start typing, there is a 1 or 2 second lag before it starts showing letters I touch. For example if I open messages and start to type "Apple" it comes out "ple" -- the first two keystrokes are not recognized.

Reset iPad

Hold down the Sleep/Wake button and the Home button at the same time for at least ten seconds, until the Apple logo appears

Note: Data will not be affected.

Then a Visit to an Apple Store or AASP (Authorized Apple Service Provider) is the Next Step...

Be sure to make an appointment first...
