If DRINTERVAL in your onconfig is set to -1, then it's synchronous;
otherwise it's async. Current setting is also displayed in 'onstat -g dri'.

For performance reasons, we use async mode. We have never had any problem
with lost data, nor with big lag times. Replication almost always occurs
within a second or two, with one server in Sacramento and the other in
Minneapolis.

Suggest that you RTFineM, if you haven't already -- Admin Guide, ch. 19-20.

thanks, Paul.
Can you tell me if there is a way for me to find out if the
replication is currently in synchronous or asynchronous transfer
mode....?
Thanks,
Tom
