Hi!

We need to be able to handle large files and I notice that after editing at the end of such a file there is quite a long delay in which Eclipse is unresponsive.

I have disable the code folding which I know is a culprit, but it is still too slow.

Do you think there are operations that could be run in the background but aren't?

Do you have any suggestions as to what else I could disable?

best regards,
Vlad

A related question about disabling functionality for large files: I know how to disable things for all files, but in this case I need to check how many lines the file has and decide accordingly. How can I get a reference to the Eclipse document? I suspect I have to inject the right object, but I couldn't find which on that is.

Thanks in advance,
Vlad

We are already running most probably expensive things in background
(reparsing, validation, semantic highlighting). I'd recommend to find
the hot spot using a profiler.

Well, this depends on from where you look :-)
XtextEditor.getDocument()
is a good start. Also have a look at XtextDocumentUtil
