Perfomatic:UI

Design

Designed by Chris Howse

Implementation

• bug 601796
• Perf-o-Matic demo

Missing features from current design

• dashboard ->
  • toolbar ->
    • product - not implemented
    • platforms - not implemented
    • top tests - not implemented
  • data grid ->
    • row/column should not scroll
• custom chart ->
  • running time - time delta/time delta % not implemented
  • show changesets - needs design work
    • may need hgpushlog work to link directly to changesets
  • export CSV - server broken
  • link - needs url shortener
  • embed - not implemented

Performance optimizations

• split up JSON files as discussed in status meeting
  • look into constraining by date range
• set Last-Modified tags to all JSON
  • especially the manifest!
• add caching proxy
• improve charting performance
  • "double-buffering" canvas for flot
    • stack overflow discussion
    • custom chart is much faster if each series is written to a hidden canvas then shown when they are all complete
  • look into reducing number of points
    • flot plots way more than is actually useful when graphs are very dense, flot group discussion
  • look into flot alternatives
    • highcharts
    • RaphaelJS / gRaphael
    • Current graphserver library

Testing

• stand up vhost with old graphserver, pointing at nightly database, for QA comparison
• set up lint and tests on Hudson
• stand up auto-update for code (5 minutes) and DB (nightly)
