Issue/Introduction



Which Max Heap size (-Xmx) is recommended for app service. 
It seems always to use 2GB.
Is there any best practice for memory utilization?

Environment

PPM15.x

Resolution

The "Tune Sun HotSpot JVMs" section in Manual says below. 
" As a best practice, set this value to at least 2048m (2 GB), even for small installations. For improved performance and fewer out-of-memory errors, set this value to 4 GB or 8 GB for larger datasets. For example, -Xms1024m -Xmx4096m.".

Recommend to increase Max Heap size for app service to 4GB.
