Sharepoint -- Macro-enabled file -- Saving File

HI there,

We have a macro-enabled file that is on Sharepoint .  The file is 14.9 MB, potentialliy even larger once we add more data.

Whenever a user opens the file and tries to add date, it is very long to load and save.

We don't have the same problem with M drive though.

QUESTION:  Is there a way to 'speed things up' in uploading files /saving files on Sharepoint?
