Issue/Introduction

Here are some settings to check in order to improve DUAS v6 performance.

 

Cause

After upgrading from v5 to v6, some clients complain about performance.

Resolution

Increase java memory allocation of UVC ->
Change the memory value (heap) for Java in the univiewer_console.bat file like this:

-Xmx = assign maximum memory for java -> increase to 4096 instead of 512
-Xms = assign initial memory for java -> increase to 2048 instead of 256

You can increase the maximum value according to the memory capacity of your computer


Node Technical Settings ->
Change the Cache: Initialization for object names from 200 to 20000, or to a value which is greater than the total number of objects (uprocs, sessions, tasks and resources) that the client has.

For UVMS ->
Increase Synchronization and Monitoring parameters:
- Maximum thread to handle connections = 2000
- Node Status Verification Cycle = 300
