I'm willing to get out the stopwatch and retest now that I know more. There was a question about the which of the algorithms (LZMA, NRV, UCL) is safe for GPL software. A quick review of the UPX web site did not give me a clear answer on which one was used when I specified "-9 --8086" for options. Does anybody know off the top of their heads?
