Poor performance in Flash-based speed tests can be related to add-on conflicts and certain Flash features. If you have not already tried these:

(1) Disable protected mode (Win Vista and Win 7 only)

See this support article from Adobe under the heading "Last Resort": Adobe Forums: How do I troubleshoot Flash Player's protected mode for Firefox?

(2) Disable hardware graphics acceleration in Firefox and in Flash

(A) In Firefox, un-check the box here and restart:

orange Firefox button or classic Tools menu > Options > Advanced > General > "Use hardware acceleration when available"

(B) In Flash, see this support article from Adobe: http://helpx.adobe.com/flash-player/kb/video-playback-issues.html#main_Solve_video_playback_issues

(3) For video issues, make sure your RealNetworks add-ons are the latest versions
