Application slow after pega 8 upgrade

Some of our applications are slow after pega 8 upgrade, the slowness is noticed when application running on clustered environment. Its working faster in single node environment. The issue is around , looping thru data page , our app dynamic reports shows the slowness is here.


We upgraded from 7.21 to 8.24. Anyone has idea or facing similiar?

Are you getting any thread dump in pega rules logs.What all alerts you have observed in pega alert logs.I suspect this is due to pega0005 alerts .Please let me know alerts captured in pega alert logs.

Hi Abhinav,
I dont see many PEGA005, but seeing PEGA0011 alerts only. Also I enabled logger and found out that, accessing data page in clustered environment takes longer time. This application developed in Pega 5, upgraded to 6,7 and now 8.24. The same app works better in single node. so is there any performance issues with Pega 8 DP access in multi node environment?

Hi Hussain,

What's the scope of data pages,Can you flush out all the datapages at the end of activity.There is some memory consumption issue with data pages set to requestor level scope.Please let me know scope of DP .

Pega0011 means service takes more time,what all operation that service does?

The scope is Node level, not sure in Pega 8 any memory issue for node level too.
