From the 6.2 machine, ping the 7.0 machine. Note times. 3. From the 7.0 machine, ping the 6.2 machine. Note times. 4. Try loading heavy web pages from each. Make a nasty one with lots of graphics and crap. Note which loads faster (6.2 every time). Actual Results: The 6.2 machine served faster and more reliably. The 7.0 machine tended to hang under heavy loads. Expected Results: 7.0 should have served identically or better. Please feel free to contact me and I'll be happy to go re-create the scenario. The machine composition upon which I was running 7.0 was: AMD K6/3 800MHz CPU, 196M RAM, 60G of IDE disk (2x30G), ATI RAGE-II video (no desktop, bare server).
1) 7.1 should have better performance than 7 out-of-the-box One important change is when in the process access control is implemented 2) remove /etc/hosts.{allow,deny}, use "only_from" inside the xinetd config files or even better - firewalling
