Tune up an upgraded Red Hat CodeReady Studio
Try to start codereadystudio with the -clean option when it is slow after an upgrade.
I worked with Red Hat Code Ready Studio version 12.19.1 for a while. And already several months ago version 12.21.0 was released. Halfway December 12.21.1 came GA.
Earlier I already tried 12.21.0, but it was incredibly slow. It was unworkable. So, I put it aside and went back to the 12.19.1 version. Today, I decided to retry 12.21.1. But, with the same result: unworkable slow.

Where $CRS_HOME points to my Code Ready Studion home (/app/redhat/codereadystudio-12.21.1).
And then I monitored it for a whil with $JDK11_HOME/bin/jconsole. But, to no avail.
At the end of my rope, I decided to scan around known issues section in the Release Notes. And there my eye caught the following:
So, I simply restarted my codereadystudio with the -clean option:
After that Code Ready Studio runs fine!
