ATG-Endeca Oracle Commerce site performance degrades and toll on application tier memory - Best Practices

Problem Statement:

ATG-Endeca Commerce site performance degrades and toll on application tier memory

Solution:

If aggregation is defined in the Endeca with below configuration(allbins=2) and there are so many sub records are rolled up per product. 
/atg/endeca/assembler/cartridge/handler/config/ResultsListConfig
subRecordsPerAggregateRecord=TWO 
You can fix it as below:
1) Configure records Per Aggregate Record set to 1
 atg/endeca/assembler/cartridge/handler/config/ResultsListConfig
   # For aggregate records, sets the number of sub records that should be included in the results
 subRecordsPerAggregateRecord=ONE
