Hi Everyone,
Is there anything I can do to make WbSchemaDiff faster? It took 10 min to compare just a handful of table, and 35 minutes to compare 190 tables. TIA.

WbSchemaDiff does a lot of requests to gather all needed information. In theory, this could be done with fewer more complicated SQL queries, but that would mean I have to re-implement the whole JDBC API manually for each and every supported database.
I don't know which DBMS system you are using, but this is especially true for Oracle where access to the system tables and views is quite slow anyway.
As WbSchemaDiff should only be used in exceptional circumstances, I don't see a big problem in it being a bit slow.
