Question

I have some interesting notice with scrolling performance on UITableView with cornerRadius, borderWidth and borderColor e

Answer 1

CALayer having shouldRasterize property for this type of performance issue. Just set

self.tableView.layer.shouldRasterize = YES;

This single line saved my lot of time and work.

Answer 2

I just found out that cornerRadius with borderWidth sluggish tableView performance by a lot. So instead of 10.f radius I changed to 5.f and performance has increased amazingly. Still not perfect but noticeably better...
