It depends. In most cases, it will just run as fine as on Linux,
sometimes it is even faster. The Linux compatibility is no emulation,
it just translates syscalls, so you shouldn't notice a performance-hit
in 99% of cases... but of course there are corner cases where it could
be that the performance of your Linux-binary on FreeBSD is not 100% as
fast as Linux.

See the Handbook for a deeper understanding of how the Linux
compatibility is working :)
