Garbage collector pause time

How can I target maximum pause time for Garbage collector in Ignition 8.1.
I would like to set it to 100ms. I know that the java default is 1 second.

Put something like this in your ignition.conf file:

wrapper.java.additional.Z=-XX:MaxGCPauseMillis=100

Replace the .Z with a suitable unique integer.

Note that it isn't truly a maximum, as that cannot be guaranteed, but a target maximum.

Do you know what is the java default for maximum pause time for Garbage collector in Ignition 8.1?

The default is 200ms.
