Issue 179: Tabbed Layout does not scale for >50 windows http://code.google.com/p/xmonad/issues/detail?id=179 Comment #2 by Braden.Shepherdson: sjanssen and I looked into this last week. Laying out the tabs appears to be O(n^2), so opening n windows becomes O(n^3). Further, the text size calculations are O(w^2) (w the longest name) and do expensive font-metric calculations. sjanssen and I agree that those runtimes should be possible as O(n) and O(w), and using a fixed-width font should remove the many font-metrics calls too. Unfortunately, these changes are in the "rewrite" category, not the "tweak" one. -- You received this message because you are listed in the owner or CC fields of this issue, or because you starred this issue.
