Hi All,

We are upgrading our Appian from 73 to 75, as we know that after 7.0 most of the process or activities get shifted from engine to jboss.

So could you please let us know the default heap size for Appian 75??...

The heap size will be determined in JBoss, using the arguments -Xms (minimum heap size) and -Xmx (maximum heap size). I believe the default will be -Xms2048m -Xmx2048m

Do you mean 60-65GB? It's difficult to say what heap size would be best without considerable analysis, but the following formula might help:
(heap size) + (number of threads)x(thread stack size) = (total RAM used by JVM process)
