Hi!

> 2015-09-29T09:44:53.808480308 0.036235s warn: Failed to disable read-ahead on '/usr/local/rethinkdb_data/metadata' (errno -1). You might see decreased read performance.

src/arch/io/disk.cc

has an ifdef'ed fcntl(fd.get(), F_RDAHEAD, 0), and FreeBSD is not
correctly defined, so it does not get called:

If you look at line 495 of disk.cc:

#elif defined(__APPLE__)

and change it to

#elif defined(__APPLE__) || defined(__FreeBSD__)

it would work.

Hmm.

I do not have application knowledge, someone has to dig into this 8-}
