Thanks, that sounds very useful. I’lll give it a try when I dive back into this. Today I got the GCD-enabled code almost back up to the performance it had on iOS before it was thread-safe and parallel. Still counts as a victory, because with more cores (as on my Mac) it’s a lot faster. Some of the speed came from not using dispatch_async for trivial blocks, some from fixing bugs in my code, some from allocating fewer objects… Slowly chipping away at it and making little gains one at a time. —Jens _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
