I think you are misleading Polygraph: benchPolyMix4 specifies that one
host can handle up to 500 req/sec. Thus, Polygraph allocates IP
addresses for one host. However, later, when creating aliases,
Polygraph notices that you provided 5 hosts and spreads the IP
addresses accordingly.
http://www.web-polygraph.org/docs/userman/address.html
Please use just one client-server pair:
TheBench.client_side.hosts = [ '172.16.1.61' ];
TheBench.server_side.hosts = [ '172.16.1.191' ];
OR tell Polygraph that each host is capable of 100 req/sec:
TheBench.client_side.max_host_load = 100/sec;
TheBench.server_side.max_host_load = 100/sec;
OR increase you request rate to more than 2000 req/sec:
TheBench.peak_req_rate = 2001/sec;
The first and last solutions are tested and should work fine. The
middle option is the right thing to do if you want to keep 5 hosts at
500 req/sec, and it should work (though you might need to adjust
netmasks, not sure). If none of the above helps, please let me know.
Alternatively, you can by-pass PolyMix address allocation scheme
(since you are violating PolyMix rules anyway), create aliases
manually using "aka", and then just tell Polygraph to use those
aliases instead of creating aliases run-time (remove "lo" interface
name from addr_space specs).
