Betreff: [amibroker] How fast AmiBroker is?

Hello,

Since one of our uses pointed out to the last Metatrader ad that gives
completely false
statements about AmiBroker speed (in their ad they were telling that
AmiBroker is able
to do 79 simple mathematic operations per second only on 2.8GHz machine
(sic!)), I am giving small example of
code that shows real actual speed of mathematical calculations in AmiBroker.

How untrue their claims are you can check by running this commentary code:

Now(); 

for( i = 0; i < 1000000; i++ ) 
{ 

  x = 2 * i + 13 * sin( i ) / (3*i) + cos(i); 
} 

Now(); 

The code consists of ONE MILLION of iterations each one
consisting of:
3 multiplications
3 additions
1 division
2 trigonometric functions

So total of 9 mathematical operations per interation. 
And if you run it on 1.4GHz machine (which is 2x SLOWER than the machine
they used for tests)
you will see that it executes in 1 second.

This gives (9 ops * 1000000 iterations) = 9 MILLION of simple operations per
second in AmiBroker.
So they misquoted AmiBroker speed by 5 orders of magnitude.

AmiBroker must be real threat other platforms if they start to spread so
untrue figures.
