My Pi does about 42Mbc/s and 1.4Msn/s

Try to get a Pi sometime. You'll adore the sheer cuteness of having a machine that small and raw to play with. Download RISC OS and enjoy a *really fun* operating system as well.

It is certainly a good approach; even on the Pi it is bearable. I'm doing some work on how to boost the bitBLT performance right now (which is not so hot) and that would make a big difference. Eventually I hope to get the Cog vm working on it as well.
But the real key is always better written systems code. Morphic has always seemed to have horrible scaling issues - with one window open it can be ok, open a dozen and     it    gri    nds   to          a      h h     aa    l     t.
A long time ago Andreas made a benchmark that timed opening a couple of dozen browsers and it was possible even on a fast machine (of the day, so say 25% of the fast machines now) to see how the last few took so much longer. If anyone can fix that problem life would be a lot better. By contrast, open an MVC project and use a couple of dozen browsers. No performance problem there...

That does help a little. It does still take a good 1sec+ top open the workspace text editing menu and at least 5 sec to open a browser.
