SQLCompress.NET provides several implementations:

• Fast Deflate (recommended): This implementation is VERY fast with very little overhead.
• Base or Benchmark: This implementation should NOT be used for compression. This is included for benchmarking purposes ONLY. It allows developers to determine how much overhead their compression libraries add to an implementation. The implementation does not compresses anything but does add block and compression headers increasing LOB size.

We recommend the use of Fast Deflate for compression purposes and Basic (or Benchmark) for comparison purposes.
