Synonym lookup super slow? How to fix?

[edeutsch]

I've noticed this for a while, but only posting now. Has anyone noticed that the Synonym lookup through the ARAX GUI is super slow? Try searching for metformin or ibuprofen or anything reasonably common, and I start hearing my CPU fans groaning and it takes 15+ seconds for something to appear. I assume this is either because so much data is returned or rendering the graph is so expensive or? I wonder if anyone else has this issue? And if anyone has ideas on how best to solve it? Return less data? Don't render the graph unless asked? This service was great when answers came back within a second, but now it's painful to use.

ideas?
