Hey blacksilva found summin ya might like.
One obsessive software tweaker to another.
Thought I'd letcha know about summin I came across today. Talking about the swappiness thing. Might not improve boottime so much. But is supposed to improve general performance and on a system with more than enough RAM ... like yours. Setting it to summin like 10 surely wouldn't hurt regardless.
Or even 0 ... but might just be me ... I prefer a safety net and scuttlebutt around the web seemed to advise that vm.swappiness=10 was about right for desktops. Without further ado ...http://sites.google.com/site/easylinuxt ... o-high:-Ub
Actually did this myself of course. Before advising anyone else to and it works as described. Bunch of people in the forums mentioned adjusting swappiness from the default of 60. But their instructions are really vague as to where to add the code or how to. Also what they described didn't work. I tried adding what they said, where they said and nuttin. The procedure outlined in the linux article in that link works.
note though: In relation to editing your sysctl.config file. With this ... in mine there was already a hash mark (#) at the bottom. So I didn't have to add another.
# <This was already there at the bottom of the file.
# Decrease swap usage to a workable level
^ So I only had to add these two lines to the bottom of the file, hit save and reboot.
When I run the terminal command to check my swappiness value. ( below )
It comes back as 10 now, like it's supposed to . I doubt adding an extra # ( hash tag ) would matter either way. Just making sure people know how to do this with their comps, if they come across the thread.
