Comment 5 Erno Mononen 2009-08-24 12:38:04 UTC 
I couldn't see anything ruby specific in the snapshots, it seems that PatchedHtmlRenderer#renderHtml that gets invoked 
multiple times by GsfCompletionItem is taking a rather long time. Passing to editor for further investigation.
Comment 6 Vitezslav Stejskal 2009-08-24 16:02:23 UTC 
200906081401-slow-creating-code-completion-for-ror.nps is somewhat different than the other three snapshots. It shows an
activity in rubyforge ReadersSupport. So, I'll ignore it. The other three show activity in PatchedHtmlRenderer and its
use of FontMetrics.getStringBounds. I'm not sure how this can be made faster though. What OS are you running? Is there
anything special about your fonts, look & feel, etc?
Comment 7 esmithbss 2009-08-24 16:11:34 UTC 
Ubuntu 9.04
Gateway m460 notebook
2gb memory
Gnome 2.x
Gtk LAF

Also happens on a Dell Inspiron 600 with dual core and 4gb mem running WinXP.
Comment 8 Erno Mononen 2009-08-24 16:24:27 UTC 
Wrt. ReadersSupport - that's the ruby debugger loop, so it can indeed be ignored here.
Comment 9 Dusan Balek 2009-10-09 15:18:19 UTC 
Strange. Does it happen under Ruby On Rails only, or is it reproducible also in the Java editor?
Comment 10 Dusan Balek 2010-11-12 09:45:17 UTC 
Most of the time spent in the FontMetrics.getStringBounds. Since there are no other similar reports since NB 6.7, closing as WONTFIX for now.
