Plan for NB 6.10 Performance improvements

This is an implementation plan for performance-related work targeted for NetBeans 6.10 release. It's based on post 6.9 performance topics and NB 6.10 performance goals. It covers work done by all engineering teams, except routine bugfixing.

Milestones

Milestones below show which tasks should be finished by given date. Completed tasks have the Image:Yes.png check mark.

July 26

  • Image:Yes.png Oleg: Renewed Comparative dashboard
  • Image:Yes.png David, Oleg: Editor typing tests - existing tests fixed + new tests suitable to test the new view hierarchy

August 9

  • David, Oleg: Editor typing tests - measuring new view hierarchy (switch -J-Dorg.netbeans.editor.linewrap=true)
  • Image:Yes.png Jarda: Go to Type - prototype demonstrating desired availability and performance: File:Uber-goto-type-cache.diff
  • Image:Yes.png Jesse: Issue 157283 - Declaratively load lookup items for Maven packaging types

August 23

  • Image:Yes.png Jarda: Dump occupied file descriptors on Unix into log
  • Image:Yes.png Jarda, Tomas Stupka: VCS-FS interaction on renaming folders -- agree on solution. RefactoringFSandVCS
  • Image:Yes.png Tomas Zezula: Index in memory for fast Go to Type (Issue 177274): automatically reserve part of heap permanently, rest as soft-references.
  • Image:Yes.png Tomas Hurka, Jirka Sedlacek: Time line in Profiler for long CPU snapshots (especially from self-profiling). See InstantFitness.

September 6

  • Jarda: Image:Yes.png FitnessViaCLITimeLine - sample any application (e.g. NetBeans startup), analyze it in a timeline.

September 20 (Feature Freeze)

  • Image:Yes.png Statistics for people who turned off checking of external changes. See scanning statistic
  • Image:Yes.png VCS-FS interaction on renaming folders -- do something. RefactoringFSandVCS
  • Image:Yes.png Petr Nejedly, Tomas Zezula: Native file listeners
  • Image:Yes.png Martin Entlicher: Fast debugger stepping
  • Image:Yes.png Oleg: Measuring project's classpath modification
  • Image:Yes.png Tomas Hurka: Adjusted UI to start/stop IDE self profiling
  • Tomas Hurka: Integrate profiling snapshots with UI gestures, make exception reporter (statistics.netbeans.org) provide new NPSS snapshots together with the UI gestures data. (May require a new format for one file holding both the snapshot and the UI estures data.)

Dropped

  • All: Measuring performance of sample projects: for selected sample projects of various size measure typical performance characteristics (e.g. a subset of comparative dashboard) to give our users some reference numbers of what performance they can expect
  • Tomas Zezula: Fill Go to Type results incrementally (not waiting on slow providers like JavaScript)
