I've tried several benchmarking applications and my favorite by far is the benchmarking suite in SK Tools.
If you download the trial version (some features are limited but there is no time limit on using them), it has the full benchmarking suite 'unlocked' for unlimited use, and tests things like the CPU's speed, bitmap rendering speed, internal storage read and right, and storage card read and write speeds.
I also use VS Benchmark which is free, and measures many of the same things, but looks nicer doing it
I saw a gain in performance from VZN 3.0 to SSK 1.2 on VS Benchmark.
So... when all is said and done we will have a 20764 OS and XIP? Scott you feel that 20764 is more stable than 21109? I do tend to agree there... VZN 3.0 was 20764 right? I definitely felt that rom was solid as a rock. I've had a few random lock ups on SSK 1.2.
