I have made some test related to the speed of apache and nginx on my new server to see which would be the best for running. Of course the test have showed me that nginx is the best, there is no fight and no question about it, but in my test I have found one thing weird. I have test botch apache and nginx with an image, a small 1-2k image, but the ab results I have this:

Apache 2.0.63: Document Path: /img.png Document Length: 1463 bytes

Total transferred: 17538570 bytes HTML transferred: 14695835 bytes

Nginx 0.6.32: Document Path: /img.png Document Length: 1463 bytes

Total transferred: 16841796 bytes HTML transferred: 14771911 bytes

My simple question is why?! Is nginx losing something or apache adding something, if there is perfectly the same image.

Im not so good at this kind of things, I just wanna know if there is some problems someplace.

Thanks!
