docpad-plugin-cpuprofiler

CPU profiler Plugin for DocPad

Generates cpu snapshots using v8-profiler during specified docpad events that can be loaded in to the chrome profiler. Snapshot files are generated in the root of docpad under 'snapshots' folder by default

Config

plugins:
  cpuprofiler:
    # default output path relative to the docpad root path
    snapshotPath: "snapshots"

    # events that this plugin can start and stop recording from (change to suit your docpad instance)
    # default settings
    events: [
      {
        start: 'generateBefore',  # event to start recording
        stop:'generateAfter',     # event to stop recording
        recordSamples: false      # passes the record_samples (flame data) boolean flag to the profiler, default is false
      }
    ]

Capturing Multiple Events Example

plugins:
  cpuprofiler:
    # default output path relative to the docpad root path
    snapshotPath: "snapshots"

    events: [
      {start: 'generateBefore',               stop:'generateAfter'},
      {start: 'parseBefore',                  stop:'parseAfter'},
      {start: 'populateCollectionsBefore',    stop:'populateCollections'},
      {start: 'contextualizeBefore',          stop:'contextualizeAfter'},
      {start: 'renderBefore',                 stop:'renderAfter'},
      {start: 'renderCollectionBefore',       stop:'renderCollectionAfter'},
      {start: 'writeBefore',                  stop:'writeAfter'},
      {start: 'serverBefore',                 stop:'serverAfter'}
    ]

Capture across events
