That codec may be configured with either XCodec (which does deduplication) or no codec (so no deduplication), as well as with a compressor. The compression uses zlib, and you can set the compression level, so that e.g. on a low-CPU box you might set it lower, and on a high-CPU box with a lot of data that benefits from compression, you may set it higher. WANProxy manages it by you configuring it. Deduplication is done by the data before compression, and then the deduplicated data is compressed.
