It depends on your actual usage. There are so many different possible
configurations and modules in the Nginx world.
When you *effectively* enable sendfile in Nginx, then the data won't
go through the userspace. But sendfile won't work with nginx upstream
modules.
For large data processing, nonbuffered processing is usually more important.
