I've got a project here with 16,500 files in it (75,000 if you count the subversion metadata). It's a Joomla 1.5 website with a bunch of content. I have three copies of the site in the project directory because of the way I'm merging changes from the latest Joomla SVN into my own source tree.
Needless to say switching to and from TextMate causes a considerable delay - between 5 and 10 seconds on my G4 PowerBook. I like to flip back and forth between a web browser, terminal and TM pretty frequently - at times as much as maybe a few times a minute - so I'm spending a fair proportion of my time waiting for TM at the moment.
Does anyone have any tips for speeding up TM's project scanning? Obviously I could rearrange my project to move some of the less frequently used files into another project - but I'd rather not do that if it's avoidable.
It seems that TM only really needs to rescan the directories that are open in the project drawer and any open files - a full scan could be then be done lazily if at all. I get the impression it currently walks the whole directory tree - is that correct? If it's not doing that what's taking so long?
