Wes McKinney commented on ARROW-501:
------------------------------------
Well, in my experience applications that use mmap are faster than ones that use
read(...). But the reasons for it more have to do with primitive IO access
patterns (i.e. synchronous calls vs. async) and memory management. We'll have
ample room to experience ourselves
