I do have a tendency of doing that. :(

I'm having a difficult time distinguishing where that line is.
How you tell the difference between the two?

I don't know if it changes anything, but this would be ran once daily, 
right after I pull the feed from the Realtor Assoc. It averages ~15K 
properties but that translates into ~450K inserts into the 
carmls_features table.

 I've never timed INSERTS on my server before, but you got me 
curious. So, I gave it a go using your code (which worked great,
btw) and here's what I saw:

453866 records inserted
total time 98.8076000008 seconds
average time per insert = 0.000217702141162 seconds

That's a lot faster than I thought it would be, but wouldn't it be
faster if it wasn't going back and forth between PHP and MySQL?
