This document contains the results of testing different configurations of modules with changes in JAVA_OPTS replacing XMX with MaxRAMPercentage. Memory utilization, The main KPI for these tests are Memory consumption of modules, Data import durations and Check-in / Check-out response times and Data Import durations for MARC Bibliographic records should be compared.
