Hehe, it doesn't seem any smaller, but at least it is up to date.

Thanks to both of you.

with regard to fstab mount options in the article

1) i am missing the "defaults" option, or can it be left out?
2) would it not also make sense to use "nodiratime", too?

default incorporates the options rw, suid, dev, exec, auto, nouser and async. You can either use default or explicetly add all the options you need. Noatime includes nodiratime, as you can read in man mount (2) (http://linux.die.net/man/2/mount)

Nice update.
I have seen recommendations to set AHCI mode in BIOS for SSD. I never did get round to it though.

Maybe this is a stupid question but I don't know better.

Would it be possible to incorporate this in the siduction installer?

To be able to choose "sdd" as option during install and get all or the most of this optimizations done by the installer.

Trying to follow this tutorial I got to this:

Quote

Multiple sources that you can find with a google search indicate that, for SSDs, the “deadline” and “noop” schedulers perform better than the default “cfq” scheduler, with deadline getting the most recommendations. Set the scheduler in /etc/sysfs.conf as so:

I can't find that file, I have a file called  sysctl.conf in /etc. Shall the sysfs.conf be created?

Under part 6 of the tutorial there are som things that needs to be changed:

Code: [Select]

dd if = /dev/urandom of=tempfile bs=512k count=100 oflag=direct take away the spaces around "=" to get it to work dd

Code: [Select]

if=/dev/urandom of=tempfile bs=512k count=100 oflag=direct and

Code: [Select]

hdparm - fibmap tempfile shall be

Code: [Select]

hdparm --fibmap tempfile similar to

Code: [Select]

hdparm -read-sector 1234567 /dev/sdx shall be

Code: [Select]

hdparm --read-sector 1234567 /dev/sdx
Just tell me if I'm wrong, please

I can't find that file ...

You need to install the sysfsutils package (https://packages.debian.org/wheezy/sysfsutils).  Sorry, I did not realize everyone does not already have it.

I think your other corrections are all correct.
