[dba-SQLServer] SQL Server 2008 compression

ya can't! literally, this thing is engineered back in the days when database
engines couldn't support this many tables and there are literally tables
within tables using blobs or other techniques, so there are actually more
than 70k tables, but only slightly over 70k physical ones.

going back to your original post, I didn't realize you ment DATA compression
vs Backup compression.  You will want plenty of cores of course since there
will be some overhead on CPU usage.  but because there is less data being
handled you will see some speed increases especially in a redundant database
like yours, it consumes less I/O so you can push more data through it.  It
seems that you would benefit most from what they call ROW compression;
