I have found that the best way to get my iPhone and iPad to work reasonably well is with the Restart/Reset method:
Press and hold the Sleep button while pressing and holding the Home button.
After Restarting, the offending "iDevice" it will work for awhile. When it slows down again, and it will, Restart it again.
I believe that most of the problems with iOS 8 are pointing back to the well documented WiFi issues.
