Typing within the master's work area is slow on my computer (while it is fine in 2.2.2 and 2.1.5). Maybe this just has to do with some debugging running in the background or so?
Profiling shows that calls to BufferParams::isExportableFormat are numerous and expensive when doing char-forward (33% of the total amount of CPU). This is called from GuiView::updateToolbars -> GuiView::getStatus. There is room for improvement, but this is not new behaviour apparently. I also found that calls to TabWorkArea::updateTabTexts are expensive and repeatedb. This amounts to 31% of the total amount of CPU, shared between QTabWidget::setTabText and QTabWidget::setTabIcon. TabWorkArea::updateTabTexts is connected to the signal GuiWorkArea::titleChanged. A minimal working example to reproduce the slowness could help. You can also try to profile your installation yourself with callgrind (you will have to adapt for windows the instructions at https://wiki.lyx.org/FAQ/FurtherHelp#profile) Jean-Marc, could the calls to TabWorkArea::updateTabTexts have to do with your work on improved titles?
