Golden Gate EXTRACT in Recovery Mode - anyone have experience with this?

Taking two snapshots of the extract show tihs information. Seems to be "recovering" VERY SLOWLY. I'm wondering if there's any way to improve that speed or what.
The lag is falling futher and further behind. Currently at 8+ hours behind.

The replicats were hung up this morning and we restarted both the extracts and the replicats and now the extract is in recovery mode and WAYYY behind it appears.

Just curious if anyone had any experience with this and could offer monitoring steps, general encouragement, words of warning, gnashing of teeth, you know, the usual....
