Re: [Pharo-users] Creation form from PNG file very slow on Pharo 4 and 5

Hi. I am not understand why you need to load images on startup? Why you not save pharo image with preloaded png files? With that case you will get immediate startup with ready to use forms.

You won't be able to get much more than 60 files opened/s on a disk. Stephan

there is no need to update the catalog, my project is in github and catalog always loads the latest github version .

Re: [Pharo-users] Morphic is super slow

by Henrik Nergaard

Both the syntax highlighting and critics run their own background process to do work. The general Morphic UI runs at priority 40, critics at 39 and 30. This means that highlighting will not be computed before the critics have finished evaluating, and if there is too much work in the UI thread both of these will take forever.

Re: [Pharo-users] Morphic is super slow

by Dimitris Chloupis

Hello Ben with your help and some more digging around I managed to solve my issues and I am now also able to update the taskbar button moprh without any major hit to my cpu. Pharo is now at 6-7% of one core which is not bad at all. So what you mention does not seem to affect my performance. However there is still the problem of ChronoManager taking over a second to open its gui . The problem with the loading of image is purely on how PNG are loaded. For example if I profile ChronosManager open I get 1241 for my the initialisation of the class out of this 800ms are wasted just loading the pngs with this summary 48.8% {794ms} Form
