Available RAM issues

Hello,

I’m running Avast Mobile on a Nook HD+ running CM12.1 that
does not have much RAM. I’ve noticed that two processes
associated with Avast - InAppBillingService (Google Play
Store) and ServiceMeasurementBroker(Google Play Services)

  • combined can increase to greater than 100MB of RAM.
    Is this normal or can it be reduced?

Thanks

Perfectly normal.
