    Ubuntu 11.04: i686 vs. i686 PAE vs. x86_64

    Phoronix: Ubuntu 11.04: i686 vs. i686 PAE vs. x86_64

    At the end of 2009 I published benchmarks comparing Ubuntu's 32-bit, 32-bit PAE, and 64-bit Linux kernels. Those tests were carried out to show the performance impact of using 32-bit with PAE (Physical Address Extension) support, which on the plus side allows up to 64GB of system memory to be addressable from 32-bit machines, but is still significantly slower than a 64-bit kernel and user-space. In this article the tests have been carried out on modern hardware and with the latest Ubuntu 11.04 packages to see how the three kernel variants are performing in 2011.

    While I agree about the poor coloring scheme, at least the positions remained the same throughout all the benchmarks and they where in the same order as the labels so the color did not matter that much.

    I wonder though what made Apache2 bork on the 64-bit version, it's basically the only test where 64 is slower than 32.

    Not to talk about the superior rendering, the tab interface, 3D support (admitedly not used much) and the possibility to tweak everything to your taste. When it comes to PDFs, I'm yet to see anything that approaches the bar set by acroread. Having said this, I recently discovered an impressingly fast and keyboard-driven pdf viewer that I use for quick & dirt document checking: MuPDF. For that use case, I recommend it over Xpdf, Okular and company. For those who care about it, I suggest PDF-XChange for document annotation and form-filling. It's got a gratis version and (for once) it works perfect under Wine. Forget abot PS trickery, loading documents in Inkscape or nonsense like that.

Canonical should ship the beta of Adobe Flash 10.3 "Square" 64-bit whenever a user requests a flash install (or if they check the third-party software box at install-time), thus pressuring Adobe to finalize 64-bit support and make Flash update releases of 64-bit in lock-step with 32-bit.
    They need permission from Adobe to redistribute that plugin, and last I heard about that Adobe doesn't want to give this permission...

    are you serious?

    I mean, do you really consider ditching flashplayer for gnash or lightspark to be a viable solution for a company like canonical (dare I say a viable solution at all)?

    I know ubuntu targets newbies but people who are likely going to try ubuntu aren?t going to be xenophobes. Their going to have some understanding as to what 32 and 64 bit are and assume that if ubuntu is recommending 32 bit its going to suffer 64 bit issue on the scale windows did.

    Nexuiz 64-bit

    Yes, Nexuiz does include 64-bit binaries.

    As anybody can see, on average there is actually slight improvment in terms of performance on PAE-enabled systems. But I would attribute this to the fact that system have then a bigger filesystem cache. To really show how it affects perfrormance, one would need to perform tests on 2GB system. Anyway, nice it works good, especially, as I use PAE because of Xen.
