At the end of the section "Source Code Changes":

"We have measured their execution cost and have found so significant
overheap when running G1 with and without Shenandoah code."

I'm not sure I understand "found so significant overheap", can you
please expand ?

I read that Brooks pointers have not be often be considered because of
the high cost associated with indirection, but a blog from Roman
(https://rkennke.wordpress.com/2016/02/08/shenandoah-performance/)
seems to show that perhaps this belief should be re-evaluated.

Do you have any further insights that you can share on the good
performance of Shenandoah ?

Thanks !
