DUAS6: uxsubjob / uxstpjob / DQM slower than v5

Products

• CA Automic Dollar Universe

Issue/Introduction

When testing Dollar Universe 6, the performances of the commands uxsubjob / uxstpjob or the bench of the submission of a lot of jobs to DQM takes longer than version 5.
For example:
a) On Dollar Universe 5.6, uxsubjob takes around 8 ms, whereas in 6.9.21 it takes around 12ms (setting IS_BATCH_ENV_LOADED=Y on the environment).
b) On Dollar Universe 5.6, uxstpjob takes around 7 ms, whereas in 6.9.21 it takes around 12ms (setting IS_BATCH_ENV_LOADED=Y on the environment).
c) DQM submission to a logical queue with Job Limit set to 1 job:

On Dollar Universe 5.6, submitting 1000 jobs ( that exit immediately) take 60 seconds 

On Dollar Universe 6.9.21, it takes around 105 seconds 

Environment

All OS, but uxsubjob / uxstpjob only work on Unix/Linux.

Cause

Difference of architecture between version 5 and version 6.

Resolution

This is expected behavior due to the different architecture of the version 6 compared to version 5.
A security layer has been added in all components, additionally the new way of reading the environment variables ( values.xml + variables.xml ) may provoke some longer response times to command line / DQM components.
