i already saw that page, yes.

from the comments:
"Even though cloudflare advertises that there are no bandwidth limits, there is a limit. I guess it’s not a fixed rate but I recently got an email about that (I double checked the sender)."

as i said, 'cloudflare' is presently faster than incapsula. however, if you watch the video in the link i posted you will see that incapsula offers/offered better security than cloudflare's apparently non-existent anti-hacking system. the load testing that was quoted in the page you gave me is from loadimpact and the test was not optimally set up to ensure the correct servers were being tested globally - as far as i know.

from my own experience, so far, i prefer incapsula. though my site is not busy presently.

Thanks for sharing!! Currently I am looking for speed.. But just in case I did not understand security for the site normally if I  need to secure my site I would prefer SSL over my site and also  I compared both solution everything seems same to me and I need to read more to understand security topic and need to get familiar with "incapsula"
