The *relative* latency overhead of replication increases when using
BBWC (Battery Backed Write Cache) on your "local disks",
because the entity compared against (latency of "local disk") decreases
("percentages lie").
Of course, _overall_ drbd latency _decreases_ when using write cache.
unfortunately there is no archive available of this webinar, as we had
problems with the audio quality and then with the recording.
hopefully we can sort out these problems soon.
we expect to put online a recording of the next session.
