I just profiled a really bad page, and it told me that the culprit was memcached::load_items, called nearly 300k times and taking a whopping 16 seconds!

The problem is, I use that function from dozens of places. Is there any way to see a stack trace or calling tree to find out what function is actually using it so much? This was quite easy to do with Zend Development Environment (ZDE). I am looking to switch from ZDE to Nusphere though.

I just had a similar requirement, and found this while looking around...

Hope that helps
