    Just for the record, I'm building three books of over 1000 pages each (1300,
    1500, and 1700 pages) using the PostScript backend. The size of the
    resulting PS file is as high as 167 MB. XEP takes its time on these even
    using -Xmx1000000000 (24, 31, and 22 minutes, respectively), but it does
    seem to scale even to quite large and complex pieces of documentation. One
    of the books is very graphic intensive, another has a lot of tables and
    graphics. The third is mostly text, but still has a fair amount of
    formatting variety.

    Holy Cow.
    So far, -Xmx228mb has solved my problem. Time is now < 55seconds (compared
    to 4-9minutes), and memory only climbs to ~100mb.
    What a difference!
    These numbers are for:
    WinXP pro
    Athlon 800mhz
    512mb pc100 ram

    XEP churns for ~4 minutes (at about 80mb memory use), creating a pdf.
    I have added the -Dcom.renderx.xep.VALIDATE=false. The result is a 0kb pdf
    (sequence [master-reference delivery-sequence](flow [page-number 1]Exception
    in thread "main" java.lang.OutOfMemoryError
    I have an xsl, and xml that will reproduce this. Who wants it? The
    resulting fo file (from the transformation) is ~1900kb.
    If there is more recommended tuning, please let me know. I've just
    introduced this into a production environment and we haven't made it through
    the first day.
