I just downloaded fresh copies of CodeIgniter-2.2.1.zip and CodeIgniter-3.0rc3.zip.
Installed them both on my box NO changing anything 100% default.
Ran ab -n 1000 -c10 http:... on both a few time to heat the opcache.
CI3 might be a little slower but nothing I'm to worried about.
Something that small could have been from me switched windows on my local box or something.
It's so close it's not even worth my time to push the testing up to my servers.
My results are below.
