I added JVM memory by modifying / bin / openfire. sh.
OPENFIRE_OPTS+=" -Xmn512M -Xms2048M -Xmx4096M"，
I only saw in the installation guide, - Xms, and - Xmx.（http://download.igniterealtime.org/openfire/docs/latest/documentation/install-guide.html）
I don’t know if the value of - Xmn has any effect on the system.
Hope the friend who is familiar with JVM answers!
-Xmn is the size of the heap for the young generation.
If you’re not sure what that is, I suggest leaving it alone.
FWIW, more recent versions of Java require far less tuning, IME, than earlier ones.
