Editor lagging issue

[Dragonwarp]

I play a heavily modded install on a computer that was never designed for gaming, and it has a bad framerate and in the editor screens, it frequently stops running for up to around 50 sec. I get little extra lag in-flight, (due to basically exclusively part packs) but whenever I pick something up in an editor, it occasionally just stops doing anything for a bit, and its getting on my nerves. I play in 1.3.1 (on this install), so are there any mods that stop this? I know about ATC, but it's for 1.2 last time I checked...

Check out MemGraph, it might help out. 

Or, consider upgrading the machine.  Not the most pleasant of choices, but may be the only ultimate solution.
