Jan do you have a scenario where we can see the performance issue?
Hmm...actually not reproducible one. Here's the story:
It happened me couple times that the CPU (core) usage was 100% when I typed in Nautilus. When I stopped typing, CPU usage went to 5% (which is "normal" IIUC).
I saved the image when it exhibited the performance problem, but the other day it failed to open at all. VM crashed before opening the window (log attached if anyone's interested - from the trace it looks like freetype plugin's doing something wrong.
Funny enough after not having time for this for couple days, I tried again and the (i) the image does start and (ii) it does no longer exhibit the poor performance.
I'm bloody sure nothing changed in my system meanwhile (no VM change, no upgrade of system libraries, etc). The image that crashed used no FFI calls except those done by system as shipped. So in the end something else seems to be broken and Rubric performance could be just a consequence. Maybe I suspected the wrong guy. Sorry about that.
Yes and no, the 5.0 Image has a problem with loading FT-Fonts at startup -> it crash crash, but not always. and there are some (other) issues with Nautilus (fast table, it is now disabled again,and some issues with rubric text for the code panel (slow and/or no highlighting)). nicolai

Hello Jan,
On Pharo 5, I don't think so (unless you want to reload the very old commits from nautilus). PluggableTextMorph will be remove so we will not put an option to switch between Rubric or that. Right. Is there a way to dig out an older image prior the switch?
What do not you like with Rubric ? It's not that I don't like it, but in my very case it burns my CPU. Looks like a performance problem.
Thanks! Jan

Hi there,
is there a way to disable Rubric in Nautilus and get back to PluggableTextMorph or whichever beast was used before? Quick search in settings did not help.
