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:

```python
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.
