run linux-deskop on OMAP3 processor

I let my 128MB DDR RAM's beagleboard to run Ubuntu 9.04+lxde desktop. It takes more than 60s  to open the firefox;  when open more than two web pages or more than two programs, the  system respone very slooooow.!

does OMAP3 has enough power to run a full linux-desktop?

is ARM processor still far away behind Intel CPU?

or does anybody try the 256MB RAM's beagleboard to run Ubuntu, how is it?

    I haven't tried Ubuntu with the Beagle, but I can say that the Angstrom distribution has good system response, have you tried Angstrom (installation instructions here)? For a Beagle specific question like this you may get more interesting responses from the Beagle board community.

    I tried Angstrom and I like it very much.
    but firefox run slow
    midori is better, but it has browsing problems.
    the speed depends on processes, not really on distro.

    I have posted this question   http://e2e.ti.com/forums/p/4956/19621.aspx#19621    about web browser and flash player and I'm waiting an answer, please.
    Thank you very much

    Raffaele, you are right, the speed depends on processes. I really want to know that, does more RAMs can improve the web browsing performance? does some body have answer?

    RAM may certainly help up to a point; but this is more of a question for the browser companies.  If you consider the PC space, much of the software you can buy at best buy lists minimum requirements like processor speed, RAM,...  A similar approach needs to happen in the embedded space as more and more software (e.g. browsers, PDF viewers...) are bought of the shelf.  However, since software can always be optimized further (e.g. for a particular processor), the best people to answer questions about RAM requirements are the software vendors themselves.

    Juan is correct that this is probably a better question for the browser vendor as to how much RAM they utilize.

    Just a thought, I think that additional RAM will only be helping you if you are avoiding using swap space, most embedded Linux implementations I have seen do not have the persistent storage available to have swap space meaning if you run out of RAM something bad happens, so I would propose that more RAM would not necessarily make things faster, but would rather allow you to open something more elaborate or have more programs running simultaneously. Of course I could be mistaken, for a real solid answer you would need to ask the browser folks.
