Why GZip Doesn't Help Direct Proxy's Performance
For direct OSB proxies, passing XML content as GZip will not improve the end-to-end performance due to extra time required for gzipping and un-gzipping. There is a service I have to deal with which is a constant headache. The service returns a huge, 1Mbyte or more, XML with all kinds of information. The web application that calls the service experiences a very noticeable delay, which affects the user experience.
