I installed FC16 from the 64 bit Xfce spin on a customer (Dell Optiplex 330) two weeks ago. He is complaining of performance problems. On analyzing the situation, I am finding him running out of RAM memory. He currently has 2 GB.
His programs freeze. Hard drive LED goes on solid. Hard drive rattles like it is going to fly apart. "free -m" says he is max'ed out. Hard drive stops and programs start working again. This is especially a pain in the neck when printing: six pages takes fifteen minutes.
I currently have him running only one program at a time, which does help.
Since the Optiplex 330 will only support up to 4GB, I was going to up him to 4 GB.
Question 1: will 4GB be enough? He uses Firefox, Thunderbird, Libre Office. And he prints to an HP ink jet.
Question 2: what can I turn off to decrease his memory usage?
I am concerned that if I up his memory, he may still have the same problem.
