Is there a performance tuning guide somewhere. I know to kick up the 
memory offered to Tomcat. That helped out a good amount for the UI.

In particular at the moment I'm having trouble with the loader. I'm 
trying to load in our legacy groups for lack of a better term, and it's 
firing up way too many threads. We have around 1k legacy groups. I can 
see from jconsole that it's easily starting over 200 pool threads. Then 
they start to time out, and MariaDB starts to complain about too many 
connections. I see in the loader config file reference to 
loader.use.groupThreads, and loader.groupThreadPoolSize, but not 
entirely sure how they work.

loader.use.groupThreads means that it is trying to use threads for each 
of my 1k groups? And loader.groupThreadPoolSize means it is trying to 
use 20 threads for each group? So is it trying to start 20k threads? 
That would seem to indicate that the right option would be to set 
loader.use.groupThreads to false. Or is there something else? I've hit 
the same problem trying to load departments, and we're a mid-sized school.

Is there anything else to performance tune the system?

Thanks,

Richard
