I noticed the PHP load on a couple of my blogs has slowed waaaaay down. I can tell it's GC since none of the other pages on the site load nearly as slowly.

The most recent is a multi-merchant store I set up as 3 columns and 15 products (5 rows). Since it was so slow, I thought perhaps limiting to 9 products might help, but there was no apparent change in speed.

Is there anything else I can try?
