We make heavy use of replication and have separate distributor, publisher and t(3) subscriber servers. A few days ago we updated the distributor from 2005 to 2012 and left the other servers on 2005. The upgrade went smoothly but since then replication has been running slow.
Is there any config setting that could be affecting this? These servers are all Win 2008 Ent R2 64-bit with multiple processors and 16-32G memory, etc.
One thing I will add is that the root cause is probably a new cpu spike. Our total cpu % goes to 80-100% now for hours and I am pretty sure that was not the case before. Again, any new config setting that might be affecting this?
If you have any ideas, it's much appreciated...
