Poor SBS server performance
Hi Experts,
We performed an upgrade from SBS2k3 to SBS2k11 end of last year and the server has constant performance issues. High RPC latency, takes a very long time to open EMC, server manager, sbs console etc, it is a 2 user network and this is quite a frustrating issue.
The high RPC latncy is the only perfomance counter issue I have notice, it spikes anywhere from 50-200 which is very high for a 2 user network.
How do I begin fault finding this issue?
Look forward to reading your expert comments!

What hardware are you running, ram, raid config, hard drive speeds, etc

Hi WorkS2011,
It’s a HP (ProLiant ML330 G6 ), with Intel(R) Xeon(R) CPU E5603 @ 1.60GHz (1.60GHz) and with 12 GB of RAM.
Running File, Mail, Print, Anti- Spam, DNS, DHCP for 2 users. There is 6 mail boxes but 2 4 are used very minimally

It's not that there are very little users it's SBS 2011 minimum requirements, it does allot more than SBS 2003 which is another reason why hardware and specs continue to grow, I believe SBS 2003 would run on a 40G partition SBS 2011 requires 160G...just making a point it takes more resources.
I would attempt to max out the memory, what does Task Manager tell you under the Performance tab, is the CPU maxed out?

Hey,
I've seen that before, im not convinced its hardware as it has a very small load.

Hi WorkS2011,
CPU is about 20% memory is between 90-98. However I know that Exchange will use as much memory as it can get

Taking SBS2003 and replacing it with SBS2011 is the new (increased) load not the minimal users.
if you open the resource monitor what is the disk queue like?
I'd start by maxing out the memory.
ASKER
The hardware SBS2K11 sits on is new hardware, the ram is maxed as its non ECC RAM.
Average Disk queue is about 4

In a server why did you not use ECC RAM?

Sorry it is ECC its not Buffered ECC
So all the performance issues in question are just as it pertains to opening management tools on the console of the SBS itself? The users themselves aren't complaining of performance issues?
What's the disk subsystem on this box? SATA, SAS, etc.? RAID?

The OS is on a RAID 1 and data on a raid 5. Users complain of emails taking a while to proccess from there outbox. Mostly Issue where the server feels slow to use, and performance counters go high on RPC latency. RPC latency should be no where close to 50 for a 2 user network.
The users in cached or non-cached mode? non-cached access could cause high IOPs and RPCs requests. Of course with only 2 users I wouldn't think it would have the amount of impact your suggesting. At any rate, if they are in non-cached (Online) mode I would switch them over to cached to see if that helps with their desktop level performance issues first.

Hy mgortega,
They are running cached exchange mode, sorry to say

Just a thought, have you tried looking at the network card?
Check drivers, cables etc.

Havent done driver updates in a while, cables are plugged in. Ill do some checks on drivers.

Issue was RAM related. We disabled Exchange and moved to Exchange online, no further issues.
