Hi,
I am evaluating sproutcore and cappuccino for use in my current project. Since I am a rails developer and I like pure javascript I think that sproutcore suits my style better. My problem is that every single sproutcore sample I have tested seems very slugish and slow on its user interface. Scrolling is very slow, clicking on buttons has a delay e.t.c. On the other hand all the cappuccino samples seem very responsive despite that fact that they are more full blown applications than the sproutcore samples.
I dont have a problem diving into objective-j although it currently makes my eyes sore. Do you guys think it is worth the trouble or are the speed issues just my idea. I really dont want to commit to something that I will not be able to optimize later.
