2019.3 script edit takes very long to reload

[aganm]

In a bare empty project, I create a new script, open it and edit a line, save the file, go back to unity. At the moment I switch back to unity from a script change, the editor freezes for about 5 seconds. In 2019.2, it’s almost instant.

Is this normal? I’m confused wether it’s a problem with my machine or unity. Anyone else getting very bad script reload times?

Is this normal?

It used to be faster in older Unity versions:
