Date: Fri, 22 Sep 2006 12:50:40 +0200 From: Erik Nordstrom Andersen <none@erik--erik-n-andersen.dk.lh.bsd-dk.dk> To: bsd-dk@bsd-dk.dk Subject: Optimering af OpenBSD
Hej folks
Jeg har en gammel IBM 560x Thinkpad (4GB disk, 32MB RAM, 233 MHz), som
jeg har omdannet til jukebox. Jeg har installeret OpenBSD 3.9, gqmpeg og
XFCE - det sidste for at få lidt slik til øjet og et panel med en stor
sluk-knap (som udfører "apm -z" så maskinen er tilbage på et par
sekunder i stedet for de i alt ca 8 minutter det tager at tænde og logge
ind). Ellers er der ikke pillet ved standard-installationen.
Det hele kører sådan set udemærket. gqmpeg spiller mp3'er til USB
lydkortet uden at hakke (jeg NFS-mounter musikfilerne fra min server),
men disken larmer en del, og det er irriterende, når jeg spiller stille
musik. Jeg har allerede prøvet med atactl wd0 setstandby/setidle, men
der går for det meste kun ca. 30 sekunder, så starter disken igen. Jeg
går ud fra, at maskinen mangler RAM, og derfor swapper.
Spørgsmålet er nu: hvad kan jeg gøre for at optimere og undgå at
maskinen bruger disken? Får jeg noget ud af at kompilere en ny kerne? Er
der noget jeg kan skære fra? Jeg har vedhæftet lidt info om maskinen.
Mvh Erik
