View Full Version : SSD guide questions

5th April 2013, 09:56 AM
I read the guide at http://www.forums.fedoraforum.org/showthread.php?t=277082

I have some questions.

Hardware: Home built desktop - 16GB RAM, 120GB Intel 520 series, 1TB Seagate platter, 3TB Seagate platter

Machine is mostly used as desktop, some web development.

Before I read the guide -

/ and /boot on SSD
/home on 1TB
/srv /misc /flac on 3TB
/tmp tempfs

/misc is like /home in that every user account has directory, used for things like torrents so the I/O doesn't impact /home performance.
/flac has my flac collection (and ogg collection)
/srv has databases and web server data

After reading guide I put /var/log on the 3TB as well.


7/ Eliminate "Elevator" disk scheduler.
adding the following line to /etc/rc.d/rc.local
echo noop > /sys/block/sda/queue/scheduler

I don't understand what that does, where can I read info on it and learn more about disk scheduler?
I hate doing something like the suggestion if I don't understand it.

8C/ Configure browser to use memory caches.
I assume that since /home is already platter, I don't need to worry about that, at least for SSD issues. Correct?

9/ Do we really need or want SWAP on an SSD ? [WEAR]
I was under the impression that if you have large amounts of memory, swap even if it exists isn't used unless it is needed, in which case performance wise the SSD seems the best place for it. Is my impression incorrect?

Thanks for comments / suggestions
