Hi, 

I did some performance tests: Scilab 5.3.0 Vs Scilab 5.3.0-SSE3

The benchmark is set of Scilab Math core functions, It is performed on Scilab
v5.3.0/5.3.0-SSE3 under Windows XP 64 bits. The processor is an Intel Core 2 Duo
E7500 at 2.93 GHz.
I used Intel Math Kernel Library(MKL). 

I used the tic and toc functions to measure the performances of an algorithm. 
I repeat the timing 10 times to get a more reliable estimate of the performance.

I compare the performance of Scilab math core operations (such as:
identity,random,zeros,ones,matrix-matrix multiply,Trigonometric
functions,logarithms, exponentials etc.)
I compare the performance with matrix order increasing.
I also compare the performance of Scilab Demos.

The CONCLUSION: 
Benchmarks on operation based on MKL will have the same result between 5.3.0 and
with 5.3.0-SSE3 because MKL uses all features of the CPU by default.
