  1. Re:TCP is too slow... Hello? McFly? on John Carmack on Coding a Linux IP Stack & Winmodem · · Score: 1
    Hello McFly yourself. The term TCP/IP is something of a windowsism to begin with. Since it doesn't support UDP [well? at all?], presumably MS figured they'd just lump them together and call it one protocol (never mind that they DO support ICMP which is certainly not TCP).

    For the record, IP (Internet Protocol) is a lower-level protocol that routes generic packets on the internet or equivalent. TCP (Transport Connection Protocol), UDP (User/Unix Datagram Protocol), ICMP (Dunno, used for ping and traceroute and such), IGMP (fairly obscure), and several other higher-level protocols sit on top of IP.

    While TCP is the most common type of packet using IP, it's certainly not the only one. UDP is also quite common at least in the real world, and almost everybody supports ICMP. Alternatives to IP are things like Unix domain sockets.

    For most developers the decision revolves around TCP vs UDP (IP is a given in today's networks), and the primary difference is that TCP is connection-oriented (ie data is guaranteed to arrive in the order it was sent, and if the next packet in line isn't at the reader yet, it blocks or returns EAGAIN) while UDP is connectionless (ie data is sent in datagrams which can arrive in any order, and readers do not block as long as any datagram is available to read).

    From this sumamry you can probably see why UDP is fundamentally better for things requiring near-realtime transport across flaky networks like the Internet - TCP is indeed quite slow for these purposes, since packets that get lost in the shuffle must be resent, and later packets have to wait for that one to get through before they can be read. Naturally there are things one can do with TCP to work around this limitation but UDP is still better. Of course, in real applications both types are used. A typical package will use TCP for control and UDP for data. If Carmack really wanted a better game development platform from Microsoft, he should pressure them to provide (better) support for UDP. Out of generosity they could even call it User Datagram Protocol instead of the more correct Unix Datagram Protocol, since anything Unix must be bad.

    What a joke. Scalability? Of what? The only area I can think of in which the PC architecture scales well is heat production. Reliability? I suppose there's a sick truth to this: PCs can be relied upon to offer low quality, terrible scalability, and atrociously bad design all around, from the processors to the cases to the i/o subsystems. That's reliable, I suppose, in the same fashion as Microsoft produces reliably bad products.

But most users, I think, are here for the technology.

    That said, Red Hat isn't always the leader. Their distribution has odd quirks, as all distributions do, and they can be annoying. But fear and loathing isn't about irritating RedHat-isms. It's about people thinking that a company which funds Free Software development, has made virtually everything they have produced available under the GPL, and has done more to actively push Linux than anyone else save for possibly VAR is going to try and take over the world. Listen up, people - Even if they wanted to, it wouldn't happen.

    I think many of the problems you note here actually have little or nothing to do with Linux. If you are trying to compare Big Iron with any Intel-Linux combination, you're going to find Big Iron more scalable. But I think most if not all of the time this is due to a lack of scalability of the x86 architecture and the components, system boards, etc. that comprise it.

    UltraLinux is known to run on a 16-processor UltraSPARC box (an Enterprise 450 IIRC) and that same version of our beloved OS will theoretically run on a 64-processor E10K, though AFAIK nobody has actually done so - they're rather hard to come by. Such a machine certainly constitutes Big Iron, though, and I'd love to see the results, whatever they show, of Linux vs. Solaris on such a box, or Linux-E10K vs almost any mainframe solution.

    Still, since all hardware supported by NT is also supported by Linux, to rank NT ahead is ridiculous. It would be nice to know exactly how DH Brown arrived at its rankings for "general business computing." Size of monetary contributions to the DH Brown slush fund? Cost of the OS? Survey of PHB's? Engineers? Users? Or did they run real, objective tests in the field or in a lab? And even if the latter is true, what tests were run and how? The article does not even attempt to inform us what the DH Brown report was attempting to assess, much less disclose any real information. There are cases where Linux may lose, especially on Intel; that's fine. But any report that ranks NT ahead of Linux has a pretty bad odor about it, regardless of whether we are considering Big Iron.
