The reason you think you are getting 1500-1700 cps outbound is that
your bundles are small - and maybe uncompressed.  Try sending large 
bundles of compressed data outbound - and I'll bet you you get around
the same 1200 cps.  We feed our sites news via compressed bundles
averaging around 800k and throughput runs anywhere from 1200-1400 cps..
