The PolicyPak-specific (aka New ILT engine or ILT 2.0 engine) caches evaluation results (in memory) for 15 seconds. So, when the same ILT filter is evaluated during 15 seconds interval the CSE uses cached results.
There is no ADMX setting to control this interval, but you can manually configure the DWORD value under Software\Policies\PolicyPak\Criteria Engine\MemoryCacheLifetime to set the in memory cache expiration period (service restart or computer reboot is required).
You can check the expiration period being used in the
%programdata%\PolicyPak\PolicyPak Core Client\ppService.log.

Additionally, if the ILT engine cannot determine a result it will use cached results from persistent cache in cases when evaluation fails. Evaluation may fail due to an error or timeout. This cache may be valid for 180 days:
