Re: Tuning /etc/sysctl.conf
Mmm... just a correction in /etc/sysctl.conf, it seems that by mistake I've copied a website link into the file.

As a general rule it is more appropriate to think of tuning in terms of the workload you intend to apply to your PC.

Hi Steve, I use it as a paticular desktop PC. Well, if you need more details about it, please, let me know. What do you think about current tuning?
