I am currently working on a database mirroring setup for 10 databases each under 5 GB.
When i enable mirroring on the Principal server, even before i actually start mirroring databases i noticed that network wait increases. I am using Quest Performance Analysis to monitor my Principal and my Mirror.
I haven't found documentation on this type of wait (DBmirror Events Queue, DBmirror CMD) and don't know if I should be concerned or if this is normal.
As i try to add new databases for mirroring i noticed that these wait events increase and at 5-6 databases network workload starts to be a problem as it rises to 80-90% although performance monitor on both mirror and principal report a maximum of 200 KB / sec transfer.
Both Principal and Mirror have a Gbit network card and they're both in the same private lan.
If you have any suggestions on what i should monitor please give me a hint.
Here is a screenshot of what Q. Perf. Analysis signals as a network performance problem.
