Ok.  It would probably help if performance could be qualified more.  
What was checked to determine that performace had been impacted?  
http/ipmitool response latency?

These requirements are obviously quite reasonable, but they are already 
satisfied by both implementations.  So the requirements that are not
satisfied by the DBus implementation would be helpful to the discussion 
I think.  I'm assuming those would be certain reponse time targets for 
different types of queries, and possibly some other general performance 
metrics around resource utilization?

For those using the rsyslog backend, I think sharing (performance) 
requirements would be a good start, as that seems to be the major 
differentiation feature.  For those using the DBus backend, it would be 
helpful to know if there are any technical reasons why they have not 
moved to the more performant solution (assuming it actually is).

I'm happy to keep the discussion going here...

Thanks,
