"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

You can change memory usage by changing msExchESEParamCacheSizeMax and msExchESEParamCacheSizeMin limits. I do not know how many domain and emails you have but the most of the time exchange will take everything what you have in the system and server then is very slow with other features.

The best approach is to utilize Exchange Server Role Requirements Calculator. This the official way on how to calculate amount of resources needed for production Exchange environments.

By changing msExchESEParamCacheSizeMax and msExchESEParamCacheSizeMin you adjust amount of memory what you want to use for exchange. I usually left 2 Gb for system kernel and 2 Gb for system application  and what left goes for Exchange. When you have DAG you may have different situation on each server. Resource monitor gives some real time view but not telling everything.
You may use some application like https://www.manageengine.com/products/exchange-reports/exchange-server-monitoring-tool.html
or use Monitoring High Availability and Site Resilience ps commands to see that everything is ok.
