Replication Latency

Hi:
Latency is very high in replication monitor even though I don't see any
commands to be applied in sp_browsereplcmds. Do you know from where it gets
the latency number from in distribution database because it is misleading?
Thanks
IIRC it gets it from the table MSreplication_monitordata in the distribution
database.

|||Don't forget to take into account the polling intervals of your
logreader and distribution agents. Even though theses agents seem to
run continuously they in fact do not. Check out BOL for the default
intervals. I think they are around 5secs. One way of reducing latency
is by reducing this refresh interval. Be careful though you need to
strike a balance between low latency and agent thrashing away trying
to get data all the time.
