There have been various discussions on agenda slowness in the past -
check the mailing list for some guesses (linum-mode, font-lock, property
inheritance, code compilation and perhaps others have been suggested as
possible causes). Sometimes the guesses pan out, sometimes not.

The most important thing you can do, imo, is to profile the code, first
when it's behaving well and then when it's behaving badly.

All you have to do is

    M-x elp-instrument-package RET org RET

run your agenda command and then

    M-x elp-results RET

to get the results.
