Many ports offer an option to compile with optimized cflags. See for
instance http://www.freshports.org/multimedia/ffmpeg:
OPTIMIZED_CFLAGS=off: Use extra compiler optimizations
though:
SSE=on: Use SSE optimized routines
It turns out that optimization options are usually off by defaul

That's great news! Thanks a lot!
Excuse me if I drift off-topic, how about -flto? LTO requires both compiler
and linker support, however clang3? from ports still calls the system
linker 'ld'. LLVM has its own linker, 'lld', but it is not straightforward,
AFAIK, to make clang3? call it.

Hi everyone,
I am running FreeBSD 11.0-RELEASE-p2 #0 on an old toshiba laptop. I have
had drm.i915.enable_rc6=7 on /boot/loader.conf for a long time (at least in
10-RELEASE) and I thought it was working.
I have only realised now the following error in dmesg:
drmn0: taking over the fictitious ran
Hi everyone,
A few months ago I got myself a new box and I have been happily running
FreeBSD on it ever since. I noticed that the boot was not as fast as I had
expected and I've realized that, while my disk is GPT partitioned, the boot
process is still BIOS based:
% gpart show
=> 34 976773
