Hmmm. I ran some tests a while ago on JAVA serialization vs. serialization to XML, and binary RPC vs XML-RPC. I found reading and writing the *binary* JAVA serialization to be around 3x slower than writing to XML and reading it back in... conversely, I found XML-RPC to be about 3x slower than binary RPC. At the end of the day, there are *huge* numbers of variables that play a part in performance. One thing I've found is that the performance of the data structures that the XML encodes is a *huge* factor. A naive DOM implementation will take ages to construct, regardless of the speed of parsing. Somewhat related, you'll find that an application-specific format is almost always fast than a generic one. This applies to XML as well as anything else.
