Hi Gary,

today my Raspberry 4 arrived, which will hopefully be my long-running 
weather computer.
I tried to import all my data on Pi3. It worked back for about 8 years, but 
then the performance crashed into hell.
The import of one year took about 1 week and was getting worse.

Now I'm starting it all over on a fresh install and report, what will be 
the result.
