I’m considering to use separate tables with JOIN or use single table, basically I’m worried about the performance.
Thank you.

This is called vertical partitioning. It can reduce I/O if you can separate less frequently used columns into their own table but will likely add overhead if most of your queries end up joining the tables. Especially if both tables are on the same disc.
