High memory usage after login

[solidity0815]

Hey there, i've recently started writing my first "real" addon (as in, it provides actual regularly used functionality). It's basically a log of all crafts by the player that provides extra information that I use with TSM.

The addon is using only slightly more than 1MB of memory atm, except on login, where it spikes to 60-120MB, before being culled by garbage collection.

Is there some way to find out what is hogging all that memory?

I'm not new to programming in general, but new to WoW addon programming, so please be gentle
