100% CPU usage on window focus
Reported by Olli | March 27th, 2011 @ 12:55 PM
Redcar uses 100% cpu if the redcar window gets focus and at
least one file (no matter what) file is opened.
Three is no logoutput which points to the problem.
I checked if any additional plugin is involved by removing them but
the behavior is the same.

It seems that it is caused by the spellchecker. If I turn it off the cpu usage is normal.

I am working with .rb files as well as .erb files.
The behavior also appear on normal textfiles. -

- State changed from “new” to “open”
This happens on any file you open with syntax checking on? That's very odd. Can you send us a sample of one of the files it happens on anyway please?

It seems the behavior changed a bit. After activating the syntax highlighting again the cpu usage is high for 10 seconds on opening new files, changing tabs, clicking a bit in redcar or focusing the window. A permanent 100% usage seems not to happen anymore.
I used simply .rb files of a rails project I'm working on.
Nonetheless i think the cpu usage is too high because every time i focus the redcar window the syntax highlighting is checked even though nothing changed in the files I had open.
I will keep an eye on whether the behavior i described on top still exists. -

If you have a project open, everytime the window is focussed three things happen in the background;
- the entire directory tree is scanned for changed files (this can take a surprisingly long time on a large or cold repository)
- any changed files have their contents scanned for declarations
- any changed files are reindexed by lucene.
You can look in the Task Manager to see what is happening and how long it takes.
