big table in Base slow, which Java? (Linux Mint)

I’ve imported an .csv into Base with 4193 rows & 80 columns. When i’m searching through this file, the search is ut-ter-ly slow. Even the Brexit is quicker … Searching the CSV into Calc gives me instant results. Also, importing in Kexi is working fine.

One suggestion is to alter the Java. Now i’ve 3 Java’s (OpenJDK version 11 and 2 version 8 - i think stayed from an update), but which one is the best for Linux?

Another suggestion is to have the bit-size the same (or 32 bit or 64 bit). How can i determine if LibreOffice is 64bit?

Are there different settings i could look at?
