I have try it on my computer. The file is rally big, more the 28 000 lines :). The parsing of such file took 918 ms and this is out of my control. I can not do basically nothing with it. The building model for such file takes from 2 200ms to 3 300 ms. So parsing and building model takes at least more than 3 seconds. If the file has more than 1024 * 1024 bytes then it's not parsed and empty parse result is returned. http://hg.netbeans.org/web-main/rev/bb6cff7bf886 Integrated into 'main-golden', will be available in build *201301100107* on http://bits.netbeans.org/dev/nightly/ (upload may still be in progress) Changeset: http://hg.netbeans.org/main-golden/rev/bb6cff7bf886 User: Petr Pisl <ppisl@netbeans.org> Log: #223237 - Editor hiccups on less then 1M js files In terms of memory fix for issue #224688 may significantly help. It looks like OccurenceImpl instances drop down from 1.5M to 0.5M on your file. I have also found a possible regression slowing down navigator. But perhaps you haven't seen it yet. web-main b29f4389304d One thing that is really slowing down navigator is ModelUtils.resolveTypes(returnTypes, parserResult); in JsFunctionStructureItem. |
Created attachment 128825 [details] hg bundle with the project I have a JavaScript project built around ~1M JavaScript file. The editor performance, during navigation, tiny edits, etc. is not very good - especially not on my older Sony Vaio with 2GB RAM. $ hg init $ hg unbundle "the_attachment" and then open index.html or bck2brwsr.js and to use the editor. Goto line, find, edit, etc.
