Based on previous batches (Manila), if case is straightforward and all your documents are complete, you will get your visa within 4 to 6 months from the time you submitted your application.
But yes, you are right, I think Singapore is also fast, but I am not so sure about it. You can check their charts too or something if they have a thread here....
Join the Manila Visa Office if you want to see how most of our applications goes.

Cheers & Good luck to all of us
