OmniRIM Performance Issues
Description:
If your OmniRIM application is not performing as quickly as you would expect, we have come up with a list of questions that will help us to narrow down the cause.
Cause:
Solution:
As with any Application Performance issues, there are many potential causes.
To investigate this further, there is a standard list of questions for which we will need some answers:
General
-Where in OmniRIM are you noticing the performance problems the most?
-Is the applications just slow, or are you experiencing errors (if so, send screenshots).
-Are all users experiencing slowness, or only certain users?
-Is the performance problem more noticeable at one physical office location more than another?
-Are the performance issues more noticeable at certain times of the day?
-While testing on a workstation, can you please run some specific test cases that describe the function being
done and the length of time taken to execute that function?
-Can you run those same specific test cases on the physical IIS Application server, and compare them with your results from the tests that were run on the workstation.
Network & Configuration
-Are you using any sort of LDAP integration or Single-Sign-On?
-Can you please do some Network Monitoring / Packet Sniffing between the workstation and the server to analyze and identify potential Network Traffic issues.
Workstation
- -Is the workstation's browser configured to allow caching (recommended)?
- -Is I.E. on the workstation set to 'Check for newer versions of stored pages' Automatically?
IIS Application Server
- -What are the system specs for the OmniRIM IIS Application Server?
- -Is this a dedicated server or are other applications running on it?
- -Is this server a physical box, or are you running any sort of a Virtual machine?
- -Are you running any sort of AntiVirus on this machine, and if so, have you set it to exclude monitoring of any OmniRIM files & applications?
- -Have you set up the application/site to be part of the Intranet or a Trusted Zone?
- -Have you set IIS up to force it to deliver a new page for each request, or are you utilizing caching (recommended)?
- -Is IIS Logging enabled (5-7% Performance hit).
- -Have you Defragged your Hard Drive(s) recently?
- -Please run some performance logging on this server, and send us the logs for review.

Be sure that you monitor counters for all instances of Dllhost2 on your server; otherwise, you will not get an accurate reading of pool space used by IIS.
