You really should not. Please use PolyMix-4 or, at the very least,
PolyMix-3.

You will find workload descriptions and PGL reference at
http://www.web-polygraph.org/docs/workloads/
http://www.web-polygraph.org/docs/reference/pgl/

The HOWTO documents and cache-off reports linked from the workload pages
may be very useful as well. You will find all our public benchmarking
results at http://www.measurement-factory.com/results/

Finally, Appendix D of Duane Wessel's Squid book talks about Squid
performance testing with Polygraph: http://squidbook.org/

I do not remember much about PolyMix-1 (it was written even before PGL),
but it is possible that your robots cannot contact all the origin
servers and keep trying. If you insist on using PolyMix-1, please use
verbosity level 10 and post console logs for further assistance. I would
not recommend relying on PolyMix-1 results though.

Thank you,
