Yes, although that was a consequence of the need to get it done

I agree.  Meanwhile, perhaps Toad should be implementing obvious
improvements independent of routing, such as connection multiplexing.
Not that the theory that multiplexing would help should be exempt from 
testing.  

Another theory is that message traffic is larger than data traffic, 
and hence compressing the message traffic would be worthwhile.  
Hand crafted binary message formats, or Huffman encoding based 
on actual traffic, or even just gz or bz2 right before encription
might help.

Hear hear!!  Some of the data may already be in the diagnostics,
but it bears careful analysis.  If the things we want to measure
change drastically before we can get enough samples to average out
the noise, we better figure out something else to measure.

Lets get a clear understandable explanation written up.  If I
can understand it, I'll try writing it.
