Standard Report Issue


I am using dhis2 tracker 2.32, everything event reports and other features runs perfect but the standard report generation, where indicators are the base for aggregate count, generates report very slow with long wait time , many times browser get irresponsive and crashed, and with high bandwidth it generates report in about 10 mins, there are about 23000 profiles only in the system.
Postgres and tomcat configuration seems be properly tuned as recommended in installation document.

Is there any mechanism to boost the performance?
