Exchange 2007 typical CPU utilization (store.exe)
in [Microsoft Exchange]

From: Luke on 25 Jan 2010 00:30 Hi All, we recently installed a monitoring package that via WMI queries and such magic (NO agent software is installed), is able to monitor what is happening across the network. One thing I notice on our Exchange server is that the CPU always seems to be busy. Closer inspection of the server (watching task manager) shows that indeed store.exe is using around 15 - 50 percent of the CPU time almost always. Now this might be nomal, having only just got this product I am not sure what the CPU utilization was like before.. but with my experience in Exchange 5.5 (and yes I know they are very different beasts) the CPU did not usually get thrashed so much. The event logs on the Exchange server do not have any errors and everything seems to be OK in terms of response time, etc.. This is a small network of about 50 to 60 users, Exchange 2007 SP1 Rollup 8 on Windows 2003 Server x64 R2. We have LCR and SCR configured to run to another server. The volume of mail being sent and received from this server is very low. The server itself only runs Exchange, Kaspersky Mail Security for Exchange, and Kaspersky Antivirus (with exclusions for System/Exchange files). I have watched the real time AV monitor to make sure nothing from Exchange is being scanned and it all looks good. I just wonder what a peoples store.exe CPU time looks like out there! Cheers.

You can turn off antivirus for a short while and see what your CPU numbers look like. -- Ed Crowley MVP "There are seldom good technological solutions to behavioral problems." ..

From: Luke on 27 Jan 2010 18:38 I should have phrased my sentence better.. we are running LCR on the local machine and SCR to another machine. I have tried turning off the Antivirus, but it didn't seem to make a difference :S I mean if you saw an Exchange 2007 server working normally, but hovering around 40% CPU most of the time, and store.exe using that CPU.. would you be concerned at all? Cheers!

Each store has a 1 hour window with the first being 1am, the second store 2am, etc.. This is for all 7 days of the week. This was setup by someone else though.. and although the stores are fairly small (not more then a few GB each) I am wondering if this is enough time to get all the work done.. I know exchange will pick up where it left off in the next window, but that doesn't seem ideal to me.
