Journal becomes very slow

We notice the ‘Task Journal’ is very slow the last weeks and months. (both Dev and Prod spaces)
Of course, we have more and more active jobs and more history.
Can you give us a quick advice to archive the old history and make it fast again ?

The journal is just an SQLite database. It's located as described here: Where is the embedded journal DB?.

If you have many jobs running frequently, delete old records from the journal. You can do it with an EasyMorph workflow.
