When should I consider archiving?
 

I launch OmniFocus on both my desktop Mac & iBook soon after startup and leaving it running all the time. 99% of my OmniFocus use is on my desktop Mac; syncing keeps the iBook current for the other 1%. I don't have an iPhone.

For the first time in quite a while, OmniFocus prompted me to "Archive completed or dropped items from before 9/1/09. 1040 items to archive."

I understand archiving can improve performance, especially when syncing with an iPhone.

As long as I'm happy with the performance of OmniFocus on my desktop, does it make sense to simply ignore (or turn off) archiving?

Do you ever search for completed actions or projects? If no or it is only very infrequently, imo it makes sense to archive just to keep your database as trim and fast performing as possible.

Add a repeating action to Archive your database each month if you need a prompt to do it.
