One of the most exciting additions to SQL Server 2008 was the capability to apply data compression. The benefits are many including reduced disk I/O and memory utilization, with a small cost of CPU overhead.
In a database that may contain thousands of objects, determining which objects and / or partitions of those objects may benefit from data compression can be time consuming and labor intensive.
Not anymore! SQL Server Compression Estimator (SSCE) will allow you to estimate the best compression for your objects. It will estimate both ROW and PAGE compression for all objects, and will optionally report the Index Maintenance Ratio (a ratio that indicates how often an index is updated versus how often it is used to satisfy queries). You can then use that information to perhaps choose a less aggressive compression algorithm for heavily updated indexes.

PLEASE NOTE: This tool leverages the SQL Management Objects to build the list of available SQL Servers. If you have named instances, ensure that a SQL Server Browser service is running.
If you have the SQL Server Browser service running, or you are executing this tool on a default instance you should see the following Authentication request:
Once you have provided authentication information you will be presented with the main screen where you should:
When the processing is complete (and this could take a while in a database with a large number of objects) you will be presented with the results:
You then have two options for saving the results of the analysis
Well that's it for now. Until next time this is…
