Plugin jank is in the category "things that may regress up to 5% as a tradeoff for other benefits". Any regression in the *chrome* process should stop ship. Regressions in the content process are not nearly so important.

Metrics

BLOCKED_ON_PLUGIN_INSTANCE_INIT_MS

BLOCKED_ON_PLUGIN_INSTANCE_DESTROY_MS

Analysis of these metrics from beta45ex2 has been reviewed and is now published.

The results:

• Only three plugins are reported by at least 0.1% of experiment participants: Java, Silverlight, and Flash.

Java

Slight improvement on init lag, perhaps a slight regression on destroy lag.

Silverlight

Not enough responses to say whether or not the init lag's differences (perhaps a slight lag) are meaningful or just noise. Destroy lag shows an improvement on extreme ( > 2 seconds ) lag, and a regression on moderate (200-700ms) lag.

Flash

No appreciable improvement or regression on init or destroy.

BLOCKED_ON_PLUGIN_MODULE_INIT_MS

This metric is pending analysis in bug 1261362.
