    perf can be used to profile the kernel. DTrace is even better if you are lucky enough to have it. Anyway, profiling tools are useless unless you can define what you want to improve. Speed is not a...

    Given that the software systemd starts is supposed to work on several platforms, that is not happening. Anyway, not much will ever require systemd. gdm is a rare exception.

    It turns out this is not strictly correct. Older Linux kernels use the ts bit on x86 to try to avoid reloads as much as possible:

    You would need to implement it and prove to Linus that it is better to use it. The general consensus is that such a thing is less efficient.

    With that said, all in-kernel SSE is done with...

    The Linux kernel does not use a FPU in general. Everything internally is integer based. The only registers kernel developers are allowed to use in general are the integer registers. x87, MMX, SSE and...

    SSE2 instructions are disabled in Linux builds via options sent to the compiler. This was a design decision in Linux to make context switches faster. Using them outside of special critical regions...

    You should look at OpenWRT. it runs on many devices shipping today that have small amounts of flash by today's standards. Anyway, there is always someone with a bigger/smaller system. It is a bad...

    You are the one suggesting that there are such people. The insinuation that I had anything to do with something like this is an ad hominem attack. While I might consider certain software to be junk,...

    If your system has only 4MB of storage, 2MB is half of it. The kernel itself is typically 2-3MB on such systems. If you add systemd, your OS will no longer fit on the system. Also, it is not clear if...

    We were not talking about me. We were talking about every other Gentoo developer. If every other Gentoo developer did not think like me, you can be certain systemd would not be permitted in the tree....

    You can do this today with sysctl. That is the UNIX way of doing it.

    /proc is from Plan 9. It was not part of the original UNIX, although many UNIX systems adopted some form of it. Linux obtained it by virtue of being a System V kernel clone.
  14. You might want to rethink when you consider the...

    You might want to rethink when you consider the fact that I am at least willing to tolerate such things in the tree. If the other developers were not like me, these things would *NOT* be in Gentoo at...

    If systemd is the reason you use your computer, I think you will be very happy with Arch.

    systemd is in our tree because 1 developer likes it, but Gentoo has not adopted it as its default. My opinion is that hell will freeze before we do. The general experience that we have had with the...

    I did say "do not expect to be able to run the Mac OS X version of Starcraft II on Linux anytime soon. Darling has a long way to go before it will be able to do something like this.".

    Eliminating the need for DirectX to OpenGL translation should be beneficial from a performance standpoint. Currently, the Windows version of Starcraft II lacks OpenGL support:

    Michael, I wrote ZFSOnLinux Linux 3.13 support within a few days of the Linux 3.13-rc1 tag and it was accepted upstream, which means GIT HEAD has Linux 3.13 support. For the purpose of benchmarking...
