[isabelle-dev] AFP tests timing out

Hi all,

for about one month now, we are continuously seeing the AFP tests 
failing on various entries because of timeouts, e.g. AVL-Trees, 
Regular-Sets, Collections.
To my knowledge, the entries have not changed. So the timeouts seem to 
be caused by recent changes in the Isabelle system itself.

Could you provide graphs of the runtime for the AFP of the last few 
weeks to identify the possibly critical changesets?

Are there some educated guesses what could have changed the performance 
on all these theories?
Should we ignore the performance drop and simply increase the timeouts 
on these sessions?
