I'm going to spend some time on this over the next few days. The 
symptoms are quite strange. Factors that seem to influence the speed 
include:

- whether connection is to a local broker or a remote broker
- whether the broker is running on Windows or Linux
- message size possibly in combination with wire format

I'll report back if I figure out anything more useful.
