[Pharo-users] Stability of Pharo 7 vs 6?

Personally, when I leave P7 open for a few hours, it slows down significantly. I have to save the image and open it back to not have any slug.

> I’m not sure if this is born out by others - but I’m finding that Pharo 7 is a bit less stable than Pharo 6 - I’m seeing quite a few seg-faults where the vm dies and terminates - both when the image is left running for a while, but also in fresh images where I do an Iceberg load of my projects. I’ve also seen a lot of weird things like corrupted fonts and keyboard focus/cursor keys not working properly.

I did notice that half of these images were the rc1 build 1436 setup (as I hadn’t noticed that the blessed 7.0 stable image has a different version number (previously, the last builds in PL Pharo 7 development - was the stable version - unless work then went forward for a Pharo 7.1. I liked to nab the dev version so that I know the build number to report it. I now see the about Pharo in the image also lists this number). Also some of my images were retrieved via zeroConf in the terminal (again, not sure if this makes a difference - but did that a lot with P6 too).
> This isn’t a complaint per se - as we need to move the platform forward and forge new approaches. So I really mention it to try and help diagnose the issues - or possibly understand if I’m doing something weird.
