Version 2.0 is much slower then 1.7 while communicate with MySQL. WHY?

I work with 1.7 version. I build big app. Everything work fine, but I want 2.0 version. Source is the same, but app build with 2.0 version is so slow. Pages loads 10 times slower. What is going on? I bought 2.0 without checking it and I AM VERY DISAPPOINTED! Wasted money for 2.0 version???

And where is possibility to change compression level?

Hello, how are you?
I am new to this software, i have a small php codeigniter application that i want to have it exe.

knowing that you used this software before, is it possible that you help up in using it to generate our exe file and make sure it is working, and how much do you charge for that.
Thank you
