Derick recently committed a patch that improves the performance of code coverage data collection in Xdebug.

Xdebug 2.0.0:
  Workflow:
    ezcWorkflowDefinitionStorageXmlTest:    ..............................................
    ezcWorkflowExecutionTest:               .................................................

    ezcWorkflowNodeTest:                    .....................
    ezcWorkflowConditionTest:               .........................
    ezcWorkflowVisitorVisualizationTest:    .................
  WorkflowDatabaseTiein:
    ezcWorkflowDatabaseTieinDefinitionTest: ..............
    ezcWorkflowDatabaseTieinExecutionTest:  ....

Xdebug 2.0.1-dev:

This makes PHPUnit's code coverage functionality so much more practical to use.

Update: Xdebug 2.0.1 has been released.

    Thanks. I was hoping it was just a patch to 2.0.0, since I'm having problems with 2.1.0. Is that the case? I don't know my way around the xdebug CVS repo very well... is there a branch that contains 2.0.0 plus this patch?

    Thanks again! this could be a lifesaver if the performance boost is as much as your example indicates.

    Now that collecting code coverage information is not slow anymore (as of Xdebug 2.0.1), PHPUnit's report generation code (PHPUnit_Util_Report_*) has become a bottleneck. The image above shows the profile of PHPUnit's report generation code at revi

    Some of PHPUnit features come with the cost of a performance penality. This posting explores the effect of the --no-syntax-check, $backupGlobals = FALSE;, and --coverage-html options. Syntax Check: disabled, $GLOBALS Backup: disabled, Code Coverage: disa
