Summary0004347: Upgrade to Ubuntu 20.04 yields slow performance
DescriptionI recently upgraded my Ubuntu to 20.04 from 19.10. Daily worked flawlessly for me w/r/t performance.

Since I can't automatically get daily I downloaded appImage from site and to my disappointment, it is dog slow.

Opening projects that have recursive fusions/cuts can take minutes. CPU pegged at 100%. The projects eventually open or update (A2Plus).
Steps To ReproduceOpen existing project


Change fusion child object and wait for refresh


Change file and refresh using A2Plus
Additional InformationNo crash, no warnings. Just performance.
TagsNo tags attached.
