thanks a lot!
now it makes much more sense
I just assumed that the computation time for convol does not depend on the contents of the input arrays, as for the FFT-based algorithms

The particular problem for which I started to compare the performance of the convolution algorithms was about convolving a very large array with a small kernel, so it seems that convol is ok, but I don't have to change all the other pieces of my code where I use convolve for couples of large (but not too large) arrays with similar size. Thanks for the improvement to convolve !
