    BTW, I have noticed on Jan Hubicka's blog that LTO brings most benefits when used with aggressive optimisations like -O3 and profiling driven optimisation.

    So it would be nice to have that option...

    I used car in a metaphore just to get message across.

    I lean toward prudent use of it in real life. I have old Vauxhall Corsa 1.7dTi ( diesel) and I am OK with it.

    It gets me where I need to be...

    BTW, I have just redone the test by dding 2.5GiB iso image from the nfs4 share on the box 5m from me in similar manney as within the tests you have linked.

    2.5GiB worth of data came through the...

    Ferrari is no faster than a pedestrian if its tank is empty and you have to push it down the road.

    It might be. Pretty soon you might discover that it would be really nice to have one box as a say fileserver and/or firewall and/or http proxy or email server or asterisk swithcpoint for home VoIP,...

    They are back. If you want to have no problems, go with Intel.

    At least WRT to NICs. :cool:

    No chip overheating, no botched-but-sold HW, no wall-of-silence from their tech support, no driver...
  7. Get away from Realtek...

    I don't ever want to see their stuff in anything I need to rely on.

    And there simply is no sense in saving on something that can be had so cheaply from intel.

    Get yourself a _good_ Gig-E card...

    maybe, but I have a strong feeling they know about those holes.

    Besides, this has made me reGoogle sh*t about LTO.

    So it sent me back to "GCC Internals Manual", which I either didn't see before...

    No. AFAIK they need easily testable small example that exhibits the error. This means that I was expected to sit down, understand what's going on and reduce bazillion files to one of a few lines.

    Few more things, worth pointing out:

    1. LTO was experimented with before gcc-4.6, it was introduced with 4.6 and by first 4.7 it was declared as pretty complete, practically ready.

    From IIRC...
  11. Nope. That's exactly the environment that it...

    Nope. That's exactly the environment that it should do best in - where there are many small things getting compiled into many bigger and those bigger being recomplied now and then. Since LTO can see...

    I've used freshest gcc I could find. Last few gcc bumps in gentoo were mine, since I couldn't wait for an official ebuild. I recompiled everything so many times.

    And even with gcc-4.8.2 and...

    So when RAID-4/5/6/etc subsystem uses SSE to calculate Q syndrome, this means that whole that time on that core interrupts are disabled ?

    IIRC x86 has some trick that enables it to save extr<a...

    1. Nope. AFAIK you are talking about -fwhole program, that was just meant as an experiment or uverture of LTO.

    Loading all sources and processing them as one is precisely what LTO is trying to...
  15. 1. kernel, glibc and other non-standard packages...

    1. kernel, glibc and other non-standard packages are not that insignificant. Kernel doesn't link to anything outside in userland ( except perhaps that one link for getting accurate time, but that's...

    To all the people that have to avoid sugar and on periodic insuline shots (aka "diabetics") I say that I just downed large Coke over enormous piece of pie. And now I feel just fine.

    Also, I could...

    I'm not sure I would want that thing in kernel just yet.

    kernel is a thin layer of code anyway. There is not much potential for sizeable speed gains there, even if LTO would work much better than...
  18. Mailbox Hardware Support

    I am configuring 3.14 right now and have stumbled in "Device Drivers" onto "Mailbox Hardware Support".

    It is described as a special FIFO system for sending messages on board between different...

    Meh, like usual. A few slight improvements on a synthetic test, with other results all over the place.

    Significant info would be how well is -flto optimisation performing and how many bugs were...

    I'd say it depends. For many applications I don't really need crypto everywhere, just on sensitive data.

    AES hardware is fine but it has its limits. Also, it means that data must go through CPU...
