You can adjust the level of compression that SVS applies when it creates a Virtual Software Archive (VSA). By adjusting this level, you can find a balance between performance and size. Jeremy Hurren shows us how to find the perfect balance.
If you have data that needs a different level of compression, you'll be happy to know there's a way you can change that (either per-layer or machine-wide). A perfect candidate would be my MP3 data layer which holds many gigabytes of data. Since the compression on MP3 files is infinitesimal, I choose to have them simply stored and not compressed at all to speed up the process.
The following setting will set the compression level machine-wide:
CompressionLevel (DWORD) = 0-19 (5 is the default)
To set this for an individual layer, place the value under the following registry key:
