Hi, For write performance reasons, even for Linux, I would avoid keeping the database files on a network drive, for H2 version 1.3.x.
Version 1.4.x (the MVStore) should be be less problematic, as the number of write operations is much lower. It would be worth a try. The number of read operations is still high, but that might not be a problem (specially when using a large cache).
