Bootstrap performance on Oracle with lots of Table

Hello,

A looong time is spent between these two logs:

1. 10:21:50 INFO  liquibase - Successfully acquired change log lock
2. 10:22:41 INFO  liquibase - Reading from DATABASECHANGELOG

This Oracle database contains many schemas with lots of tables. The problem doesn't occur on a smaller database.

Is it related to https://liquibase.jira.com/browse/CORE-1858 ?
We are using Liquibase 3.3.1
