Alessandro Presta commented on GIRAPH-474:
------------------------------------------
Your patch file looks weird...
I see you set the default to true. I think it should be false. Since this has
proven to be unsafe, it should be considered experimental.
> Add an option not to use direct byte buffers

> Using direct byte buffers makes it harder to control the memory used by

> I run the difference was about 10%), so I am adding it as an option.
