Greetings,

I have developed an Xbase-based grammar for my custom modeling language. I noticed that my Eclipse DSL Editor in which I edit the models gets extremely slow. It often hangs eclipse. I would appreciate any pointers on what can be done to triage and improve on the slowness.

Thank you,
Oleg

I would also recommend to profile it. Best when you have YourKit or JProfiler available. If none, use jvisualvm to get some insight where you waste most time. Hard to tell without any further context.
You can refer to the code base of Xtend for advanced Xbase usage.
