Reference: https://gist.githubusercontent.com/Krumelur/b8428bc14d03f0a569ed8f5b988f1281/raw/618f72b167e39660f963c5a6246a3df061296aef/GC.txt

From the above log file we can notice 2 things:

Bridge time reporting is broken, the fine grained log includes more time than what's reported on the aggregate one.


The "GC_BRIDGE waiting for bridge processing to finish" lines don't include for how long we waited for the GC.

We might be suffering from lock biasing on some workloads by this message gives us no hint at all.
