CompMax not updating in time

Hi. We have occurrences where CompMax is not updating on time on nodes with slow connection. 

Example: CompMax is set to 8 hours, but we haven't received data from that tag the last 10 hours. Other tags from the same noce with the same CompMax are updating as expected, and tags that receive a lot of data updates very fast.

If I understand correctly, CompMax is written to archive, while "real" value-changes are written as snapshot. 

When connection speed is slow; will PI prioritize snapshot over archive, and is there a built in functionality in PI that will prioritize some tags or interfaces over others?
