My typical cached server response was around 1s. Considering my server uses 12 CPUs this was really bad. But the page load is low and I didn't care to much:) Having problem with apt-get dist-upgrade  in the past I decided rather to install fresh version of debian/jessi  I like jesse because I got accustomed with systemd and jessie is finnaly on board with it. I decided that I will also cut down on number of CPUs down to just 4 (AMD Buldozer 2Ghz) and 4Gb of ram. So my new LAMP stack is now LNMP.
