Clearwell overall performance degrades slightly as the amount of documents increase. The slowdown in performance is due to several factors; from third party software, network latency , Intruder Detection Software and Anti Virus scanning to name a few.
Verify the Anti-Virus scanning is disabled or follow the Clearwell 'Virus Scanning Exclusions' (link below).
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
Set NIC flow control (if available) to Generate & Respond, also Disable TCP Chimney and TOE (link below).
3rd Party Software
Ensure that IIS / WWW service is not installed on the Clearwell appliance.
Run | Services.msc | World Wide Web Publishing Service is Disabled or not present
Active third party software and monitoring software contend for CPU and memory resources which could hinder performance.
Disable / Uninstall non-Clearwell supplied software whenever possible.
For any hardware changes (ex. added more CPUs, added more RAM, etc..) follow the instructions in the link below in order for the changes to take effect.
For Dell Servers, run the DSET utility to allow Dell support to verify the driver versions on the server (link below)
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)
Reboot the Clearwell appliance to place all idle application memory back into the Application Memory Pool resource.
Clearwell loads the index for every active case. As additional cases or documents are added, performance can decrease.
Clearwell has a limit of 100 cases per appliance. If more cases are added past this set limit it could result in extreme performance degradation.
Clearwell has a limit of 10 million unique items per appliance. If more than 10 million items are indexed it could result in extreme performance degradation. For more information reference the link below.
Archiving non-active cases reduces the degradation.
It is recommended that your Clearwell appliance is at the highest patch level. There are various patches available for each version as described in the articles below.
