XBM was once a high performance and useful facility, because it avoided the overhead of traditional initiation. In particular, it was popular at universities where a large number of standard student compile & execute jobs could be processed efficiently. But a decade or so ago IBM removed this version of XBM, and replaced it with one that is best described by their own words in the JES2 Init & Tuning book: "Note that the majority of the previous benefits of using the execution batch scheduling facility no longer exist. You might want to convert jobs that currently use the facility to jobs with the appropriate execution JCL as soon as convenient." Today's XBM is just a slightly simplified way of submitting standard jobs, and offers no performance benefit.
