It is 69->80.5s between 141127.61083 and 150113.26056 (tester was down) 66->69s between 141123.15275 and 141124.01653 60->64 between 140807.80282 and 140808.66762 Now the other tester shows 59->50 between 150112.41636 and 150113.13858 51->53 between 141124.14999 and 141123.43031 45->48 between 140807.01584 and 140808.72560 Can we, please, restart the frescobaldi tester? It is down sine 23rd.

Last one is ipa-cp change or perhaps get_dynamic_type is expensive (it has some chance for that). I will add timevar for it. The first two changes are not what I would expect. Perhaps checking these is a good idea. It may be something else comitted the same day.
