How To

- Clearwell overall performance degrades slightly as the amount of documents increase.  The slowdown in performance is due to several factors; from third party software, idle threads, Intruder Detection Software and Anti Virus scanning to name a few. 
- Clearwell loads the index for every active case. As additional cases or documents are added, performance can decrease.  Archiving non-active cases reduces the degradation.
- Active third party software and monitoring software contend for CPU and memory resources as well.


1. Verify the Anti-Virus scanning is disabled or follow the Clearwell 'Virus Scanning Exclusions' (link below).

2. Set IP4 binding to the top of the list and disable TCP/IPv6 on all NIC cards.  Also place the correct adapter on the top of the list for multiple NIC environments.
Control Panel | Network and Sharing Center | Change adapter settings | Highlight the NIC (but do not select) | Alt+N | Advanced | Advanced Settings | Adapters and Bindings

3. Set NIC flow control  (if available) to Generate & Respond, also  Disable TCP Chimney and TOE (link below).

4. Ensure the WWW service is not installed on the Clearwell appliance.
Run | Services.msc | World Wide Web Publishing Service is Disabled or not present

5. For Dell Servers, run the Dset utility to allow Dell support to verify the driver versions on the server

6. For non-Dell servers, update the NIC drivers if older than 2 years.

7. Run the Performance Counters during peak usage, on the Master, Slave and IGC nodes for analysis: (Use the two Performance Monitor Templates supplied in this article)

8. Reboot the Clearwell appliance to place all idle application memory back into the Application Memory Pool resource. 

9. Disable / Uninstall non-Clearwell supplied software whenever possible.
