Yes actually I see it as often as removeEntryForKey.Sorry, my question wasn't clear. If you take a number of thread dumps, how often do you see this method on the stack (including methods it calls of course)? Earlier you implied that it was often, but you didn't actually say that, or how often. The majority of the time? Also note that this is not related to cleaner lazy migration.
I see this 18/21 times in the threaddumpThanks. I'll look into improving that method.
Do you expect cleaner lazy migration=off will significantly improve the shutdown time?Yes. I'm not sure how to say that emphatically enough. Lazy migration was useful in the distant past, but slows down checkpoints significantly, which has all kinds of negative side effects. It should no longer be used. I wish we changed the config setting default to false much sooner than we did (in JE 5).
