This is intended for no-serious linux desktops (e.g. used for web browsing, multimedia ..etc), not recommended for any machine put up for some serious purpose... unless u know exactly what u are doing.
And i'm just sharing what i've done to 'the sputnik', my linux machine :) trying to make it fast fuming fluid, furious like hot molten lava hit by an asteroid came at 64km per second... pumbing out infra-red rays all around... and evaporating viscous bacterial colonies...!
Being a bad bit lazy... none of the following is a step by step guide to how to do it. Please do have the spirit to experiment (denatured) and install'em the apt way.. and RTFM...!! :)
For Fast Internet Browsing
run a local 'caching DNS server'. What 'the sputnik' have is pdnsd... because pdnsd is light and it stores the cache on disk.. so that the sputnik will not loose its hard earned dns cache when the power goes off.
$ pdnsd-ctl server all retest
$ pdnsd-ctl status
$ pdnsd-ctl dump | less
Fast booting and launching applications
Make a compressed image of '\usr' using a squashfs
The sputnik have an AMD Athlon X2 4200+ processor.. which consumes 65 Watts at peak usage, running 2.2GHz. The sputnik likes to run fast but green tinted, don't want to get stared when the electricity bill comes in. So... the powernowd
$ powernowd -m1 -p250 -l15 -u25
Play songs clean (with less harmonic distortion)
sputnik's on-board HD audio uses 96kHz sample-rate natively. when feed with the usual 44.1kHz audio.. it must be resampled to 96kHz. if not done properly.. the process will be a big source of distortion. so.. sputnik went in search of a good sample rate conversion algorithm. SoX, the Swiss Army knife of sound processing programs, does the job best. Since version 14.1.0, the 'rate' effect got tremendous improvements. Currently it is the lowest distorting audio sample rate conversion available around, at sputnik's reach.
Here is a comparison of the outputs generated by different sample rate converters available with SoX ; when feed with a 20Hz to 20kHz sweep. It is clear that 'rate -v' produces no distortions even till -180 dBFS. The tests are done using SoX's own signal generator and spectrum analyzer.
