I've been working with ST for a few months now, and since i always had core patches, i was only testing my apps using uncompressed with comment library. I was sure it would imply a longer load time. However I did not think it would also impact loaded-app animation&reactivity perf !
And that's quite a huge boost, more noticeable on lists & touch/click interaction.
was only smooth on a 4GS. some list were quite sluggish on a 4G.
Now it is almost perfect on a 3GS & 4G.
I'm using Assetic with YuiCompressor to compile (with .jar) all my JS & CSS to a single file.
(it looks like ST2 is broken by Google Closure compiler, will retry).
