I'm running Sage 100c Advanced 2020, Version 6.20.6.0

We have one primary company and another dozen or so secondary companies.

My accountant told me today that when he posts something in AR/AP in the primary company it is very fast - almost instant.  However when he posts something in any of the secondary companies it takes sometimes upwards to 15 minutes to post.

The primary company is very large, but the secondary companies are tiny - so I would imagine if anything it would the other way around.

All of the paperless office settings are going to the same location, on the same computer, on the same physical drive.  He said it's been this way for years, he just never mentioned anything before.

I've looked into how the companies are setup in Company Maintenance but I don't see anything different in any of them. 

Has anyone experienced this behavior or have any ideas where I can look to figure out why the drastic difference?
