Research TG performance ZFS with enabled compression

[AskAlexSharov]

We can enable compression 2 ways:

• in TG code: making code more complex and push everybody to pay price of compress/decompress db rows
• outside of TG code: by enabling some FileSystem compression. Then users can enable compression on their side if they need. But we must be able to answer question - "how well TG will perform on some FS-es with enabled compression?"

Be careful - disable deduplication feature of FS to avoid confusing results.
As I know ZFS default recordsize is 128Kb - need to check if bigger/smaller values are improve performance of TG.
