Performance degrades after update to Pega 7.2.2 (RUF Assembly)

SA-32475

Summary



After updating their Pega 7.x systems to Pega 7.2.2, users see a 5% to 10% degradation in performance in a two-node cluster used for development (Designer Studio). The impact of the performance degradation gets worse as the number of nodes increases and affects production environments as well as development environments.

Error Messages



Not Applicable


Steps to Reproduce



Unknown


Root Cause



A defect in Pegasystems’ code or rules

By running the following query a few times each day, you can see from the pzlastmodified date that pega_rules_sort gets updated frequently. This degrades performance.

select * from pmfrulesb.pr_assembledclasses where pzpackage = 'com/pegarules/generated' and pzclass in ( 'pega_rules_decisiontable.class', 'pega_rules_sort.class');

Resolution



Update or upgrade to the latest release of the Pega Platform.
If you cannot update or upgrade your Pega deployment, apply HFix-31149.
You must restart the JVM for the hotfix to take effect.
