Hi,
I was wondering if anyone who is monitoring their Exchange servers could tell me what their average is for the following counters.
MSExchangeDSAccess Process\LDAP Read Time (all)
MSExchangeDSAccess Process\LDAP Search Time (all)
I am particularly interested in the following processes: WMIPRVSE.exe, INETINFO.exe, Store.exe, IISIPM(hex)
If anyone replies, can you include your ratio of GC's to Exchange servers (locally)? I am wondering if the average is below 50 ms.
Thanks,
Mappy
Perhaps not the best example but I took a look at a bit older Exchange 2003 SP2 server with just a few hundred users on it and got these results. This server is behind two front-end servers and is in a site with two GCs. This is a 15 minute average during business hours.

Thanks. I am seeing about 20 - 40 emails in each local Exchange queue during a normal to busy business day. Thinking of either requesting another GC to be installed on the site or setting some type of GPO for "get closest GC".
Question, how many Exchange servers are refering to the two GCs on your site?
There are three exchange servers in that site. The rule of thumb is 4 Exchange server processor per GC processor. You will want to make sure that they are similar speeds though. If you have four 3.2GHz processors in your Exchange server and only 1 800MHz processor in your GC the ration doesn't work out that way.
If you trend out the \SMTP Server(_Total)\Categorizer Queue Length counter is this number similar to your local queue? Usually if your GCs aren't responding quickly enough you are going to have the messages in the categorizer taking some time too. Otherwise this might not be related to a lack of GCs.
