Piwik 1.1.0 and 1.1.1 seems far slower than 1.0.0

Since the upgrade to 1.1.0 and 1.1.1, Piwik seems far slower than 1.0.0.

Especially “live” (but other widgets too). Just an impression ?

Thats recorded in the forums in some places already.
Especially the live plugin is causing these issues currently and I think there was a bug with pdf reports too.
If you disable these there should be around the same performance as before.
