> Compressing encrypted content (as usually done on transport layer) is not very efficient
but plain XML is.
> Numbers:
> soap-doc-encrypted-not-compressed.xml = ~19M
> soap-doc-compressed-on-transport.gz = ~ 15M
> soap-doc-compressed-before-xml-encryption.xml = ~1.1M
> The advantages are:
> - Factor n less data on the wire
> - Faster processing on both side because much less data must be encrypted/decrypted (depends
on encryption/compression algorithm)
> Disadvantages:
> - Proprietary
> - Introduces new attack-vector and will be disabled by default for WSS with the introduction
of secure-processing
