Additional SOAP Compression Filter
Additionally, out of the box, the Windchill SOAPCompressionFilter is configured for compressing HTTP response data for special client (for example, Creo Parametric ) interactions, such as downloading the contents of a model.
The following additional property settings that control data compression behavior are applicable only to the SOAPCompressionFilter.
To use these property settings, add them to the wt.properties file:
• wt.compression.threshold=<size_in_bytes> -- Sets a threshold for which HTTP responses are to be compressed. The default value (0) specifies that all responses are compressed.
• wt.compression.off.contentEncodings=<encoding_types> --Identifies HTTP response encoding types (case insensitive) for which compression is switched off. The default encoding types are (space delimited): identity gzip deflate lws-deflate. Setting the value to asterisk (*) switches off compression for all encoding types.
• wt.compression.off.contentTypes=<content_type> --Identifies HTTP response content types (case insensitive) for which compression is switched off. The default content types are (space delimited): image/jpeg image/gif application/zip.

While data compression can provide a benefit in a slow network, using compression puts an extra load on CPU resources. Conseqently, if network speed is not an issue, the use of compression may decrease performance and is not recommended.
