I'm developing a custom view and noticed that drawRect is becoming
increasingly slow. The Shark has pointed out that the bottleneck is
the NSRectFill function (that calls CGContextFillRect under the hood)
that I use to draw the background of the view. I am disappointed that
such a basic operation could ever impair performance, but it does. It
looks like the bigger is the rectangle, the slower is performance.
I have read the list regarding this issue, but I haven't found any
solution. NSRectFillList, CGContextFillRect do not give any
performance gain.
My question is - is there a way to bypass the advanced path-related
stuff that causes the slow-down, and just get down to some kind of
fast drawing?
