thanks,i have see that. but, i also have a question. like in broker, if i set the jvm more than 32g, is it can work better than less memory?

The broker doesn’t really hold a lot of data in memory so staying up to 32GB is perfectly fine. You’ll also have to consider how the GC will behave - the more memory allocated, the more time it takes to reclaim resources.
