Hi,

Not sure it it can help but here teh results of a small test I found here on
the forum:

a=randn(2000);b=randn(2000);tic; c=a*b; toc,
Intel C2D T8100 (2x2.1GHz) + 2Gb ram
Matlab 7.7.0.471 (R2008b) = 1.4s
Matlab 7.0.0.19920 (R14) = 7.7s
Octave 3.0.2 with SSE3 (the installer available on the website) = 2.4s
Octave 3.0.3 (Tatsuro's build) with SSE2, no SSE3 available = 7.5s 

BTW I tried the test on an ASUS EEEPC (Intel Atom 1.6GHz + 1Gb ram netbook)
the result is 45s with SSE2 same result w and w/o Hyperthreading.
Cheers
Mickael
