Could you share your benchmarks?
Of course. Please see:

benchmark results:

Let us know should you find anything amiss.
Do you have access to an ARM system (like Raspberry Pi ?) On Intel,
volatile read is practically free - especially in micro benchmarks, when
compared to normal read. The normal read can't be hoisted out of loops
(the microbenchmark harness tries hard to prevent that)...
I can try this on my Raspberry Pi when I get home. ;-)
It would also be helpful if the JIT-ed assembly for the toString method
could be dumped in various scenarios.

Thanks,
