1) What data or information is lost when 'condensing' or splitting a file?

2) If we do "condense or split' the company file explain specifically what "troubleshooting" 

we can do.  What are the specific 'steps' we are doing other than following instructions like blind sheep. 

2) Simply opening QB pro 2020 takes over 60 seconds now compared to QB pro 2017, 

using nearly the same company file size.  Explain what processes or changes took place

with QB 2020 over 2017. 

3) Now, with QB pro 2020, simply trying to process a credit card takes longer.  Many times the pop up window does to populate with the customers information, we fall asleep watching it.  Sometimes we have to sign out and sign back in, or shut down QB and restart.   I'm gonna say that is an issue with servers on the merchant processing side, NOTHING to do with the KB of file size.
