I've recently had to make a necessary switch from J2ME SDK 3.0 to the Wireless Toolkit 2.5.2. I've noticed a significant drop in performance. Encryption tasks which used to take fractions of a second now take up to half a minute with no change in code.
Is it possible to speed up WTK? I know there's a way to increase the size of files it can take so maybe there is a way to speed it up.
