Mendix 9.6 annoyingly slow

Dear Mendixers, does anyone of you have the same experience: I updated my Studio Pro to 9.6.0 (which really looks nice with the UI reworks) but its annoyingly slow: - on copying pages or flows - it feels laggy when modifying flows - switching between tabs is slow - closing tabs is slow - opening something from the App explorer is slow And MxAssist Bot is of course switched off and my dev machine is a quite beefy HP Zbook with I7, 32GB RAM and SSD.    I’m curious bout your answers!   Regards,  Franz

Mendix 9.6.0 has significant performance issues with larger projects. As Juan mentioned I logged a support ticket with Mendix with a video and sample project on how to reproduce this. They sent it to their R&D teams for review but no feedback yet. However it’s unusable for me. It appears as if the error checking is interfering with the rest of the actions. And in our case error checking takes very long due to the size of the project. Most actions that occur during this error checking (that’s supposed to be in the background) freezes up the entire Studio Pro until the error checking completes. Even the error checking progress bar freezes up.


Hi all,

Could you please try it with 9.6.1 released today? We’ve identified an unfortunate issue in 9.6.0 that should be fixed in 9.6.1.

Sorry for inconvenience! :(
