Subject: 2D convolution performance expectation



Dear all,


I just begin to implment a 2d spatial convolution of an image with 7*7
float kernel using C++.
I was wondering what kind of performance I should expect when processing
1000*1000 images

For the moment, in release mode, it takes around 1.5sec for the whole
process. Does it sound ok or some optimization still have to be taken?

thanks in advance


François
