Linux: Slow start up time

Hello,

this was already asked here, but as there are no updates since months I forward this question here.

When on Linux, the UE Editor starts really slowly, it takes 5-10 Minutes to start it just for the project overview, then another 5-10 minutes to start the project (Yes I know that it’s possible to open the project directly, but that doesn’t fix the problem). On Windows - with the same hardware - the Editor starts very fast.

Does someone have updates or solutions on this issue? I even tried putting the whole engine on ramdisk, but this doesn’t make it faster. It seems like it’s a heavy cpu process which needs so long, but the interesting thing is, it takes 100% cpu summed up, but never a full core.
