SVN commit 7639 by avilla: - Backport patch to improve KWin performance.
"During working for an optimization in 4.8 we noticed that we do deep non-const vector copies where a const at() operation was expected. This means that we have in each frame: 4x+5xy unneeded copy operations (x == number of loaded effects) (y == number of windows). These copy operations explain the finding by Owen Taylor that KWin's performance correlates to the number of open windows. I did not retest with just the bug fix, but after my optimizations for 4.8 this behavior is gone."
