I recently ran into an interesting situation with a client. They were reporting that the application we support was having performance issues, namely it was running very slowly.
Upon investigation we found that their system partition (C:) only had 20GB total of space. To make matters worse it was also where the MSSQL DB was being stored as well. When asked what else they'd done, they reported that in order to fix the space issue they enabled compression on the system volume.
As you can imagine, the compressing and decompressing of data to run SQL queries against is most likely the cause of their performance issues.
My question is: can we resize the compressed partition just like any other without breaking everything? Keep in mind that windows refuses to do so from diskmgmt.msc (the option is grayed out).
