Oxygen editor very slow

I know this is off topic, but lots of you guys apparently use and have
recommended this editor.

I get constant 4-5 second delays when using this editor, can open a
window then close it, run a transform, even just switching between the
Outline and editor windows, just about anything will cause this delay.

Is this normal w/ Oxygen?  If so it would make the thing unusable.

Thanks.
