Yes, it surprises me also 2000 should be a split second thing.
However many operations are sluggish when the project manager is visible. Even ‘save project’ – all the rows in project manager get greyed out (this can last up to 10-15 seconds) and then saving is done. Bizarre!

I don’t even try to contact adobe support as they are known to ignore bug reports.
