"All operating systems were left with their default options during the
installation process..."

It's common knowledge that the default value for vfs.read_max is non-
optimal for most hardware and that significant performance improvements
can be made in most cases by raising it.

While it would be nice if FreeBSD shipped with a more performant default
setting, it would also be nice if mindless benchmark drones would quit
assuming that every system ships pre-configured to perform optimally in
their benchmarks.
