We have a project which consists of 3000+ C++ files, and the updating of "pending chekins" tab is extremely slow when loading project. (Integration with Surround SCM, although it was slow on Visual Sourcesafe, too). Worse than that, the updating is done in 10 file chunks, and the whole IDE freezes & unlocks repetadly (unusable) until it is completed (which takes around 5 mins). Faster computers do not help. At least doing it on a separate thread would solve the issue...
