I'm looking at a Java Flight Recording obtained from (internal) scale lab testing, based on Oxygen SR3 code, and thought it was curious / interesting that the second biggest "TLAB allocation" (85 GiB!) is the one below (top is OPNFLWPLUG-1047), long before and much bigger than other problems related to MDSAL and Akka, is the code path below, originating from genius.
I'm just wondering if IdPoolListener's update could be optimized - equals() on individual attributes instead of full DataObject?
