I have a site that I am attempting to move via the Powershell commands "Export-SPWeb" and "Import-SPWeb". However, I am concerned that the export is not working correctly. In Storage Metrics, the site being exported shows as 32.6GB. When I run the following command in Powershell, the resulting file is only 566MB... and it only takes about 15 minutes to complete.

Export-SPWeb http://intranet.company.com/sog/ -Path "E:\SOG-Export\sog.cmp" -IncludeUserSecurity -IncludeVersions 2

I would expect an export of 33GB to take much longer, not to mention be bigger in size. If everything is in there, that's a compression ratio of around 98%. As far as I can tell from the export log, though, there are no errors and all lists, groups, users, etc. seem to be included.

What is the expected compression ratio for Export-SPWeb?

Note: The site being exported is mostly pages and lists, with few actual files (documents or images) in any of the libraries. Farm is SharePoint 2013 Enterprise.
