sql server replication: Hi,

We have one publisher, one distributor and two subscriber. We run
transactional replication.

We recently upgraded all our hardware but now we find ourselves with an
unacceptable latency. When the "Distribution Cleanup" process fires it
take up to 4 minutes to run and will cause a complete replication pause
for 1-2 minutes at times.

In a perfect world, latency would always be under 2 seconds. I'll live
with the very seldom latency of 10 seconds.

What can be done to tame the distribution cleanup jog.

Nothing. You could run the distribution clean up job nightly and see how the
pooled commands affect performance.

I guess I should provide more info.

We relocated our equipment room and in the process upgraded the hardware
for all our database servers (1 publisher, 1 distributor and 2
subscribers).

We finished this move 2 weeks ago. The serious latency issue only
started about 6 days ago. We ran the same setup at the previous
location for about 15 months without latency greater than a few seconds.
So something is not quite right. Read on, help is on the way ...

After doing more research last night and this morning we find that some
of the tables that are "suppose to be cleaned up" contain more than
12,000,000 records.

So we are now approaching this problem from a different angle. 1.) Why
are those tables so big and the "clean up" job not "cleaning up". 2.)
How do we go about cleaning those up so that the "clean up job" doesn't
take so long to do it's thing. I saw some similar post so I'm hoping
that I will find some industry wisdom that can help us figure this one
out.
