Best performance tweaks?

[vsreeser]

For the following system what performance tweaks would people recommend?
it's fast already, but always trying to wring more out of it

MSI 990FXA motherboard
amd FX-8370 8-core cpu
32 Gb ram
500 Gb Patriot Blast SSD
2x3Tb hdd
1x4Tb hdd
bluray read/writer
Packaged in a nice zalman case with self-regulating fans
Azio backlit keyboard
Corsair gaming mouse

All mated to a 50inch HDTV
Internet speed is roughly 225 Mbps

My own tweaks? Not sure I'd recommend for everyone but I disable baloo (file indexer) and since I use no KDE PIM applications akonadi (contacts database) is also disabled.

My 64-bit installation with conky, yakuake and a little bit of eye candy uses about 425MB of RAM at idle.

But - unused resources are wasted resources. I wouldn't worry so much as the RAM you save is just gonna be turned into disk buffers anyway; I'm into saving processor cycles, not memory. As with any other computer disable what you don't use and think hard about what runs at startup - and if you really need to run it at startup uptime says it takes about three seconds more to start KDE than it does to start openbox on my machine - and for me that's a more than acceptable price to pay.

Hope this helps -

Move /tmp to tmpfs.
Reduce swappiness.
Reduce vfs_cache_pressure to 50 (debatable).
Set all file systems to noatime or at least relatime.
Disable unneeded TTYs.

Network changes:
Disable ipv6 if you're not using it.
Tune ipv4 for performance.

Here's some others: https://easyengine.io/tutorials/linux/sysctl-conf/

/etc/securetty shows 63 TTYs and a whole host of others tied to various serial cards. Should I just disable TTYs 3-63? I'll only ever use one or two

Mine is sitting at 10.3Gb but I have 8G in a ramdrive, playing music on firefox and running win7 in virtualbox with 8Gb ram

If your RAM usage exceeds installed RAM that thing's gotta be swapping to disk like crazy.

A ramdrive isn't gonna help you much if the rest of the system is swapping to disk; the trick here is to not use more resources than you have available. No amount of tweaking is gonna help much if you're using a couple GB more RAM than you have installed

Actually, I realize that with systemd TTYs are handled differently. They're started on demand now, so you can disregard that suggestion.

I doubt the ram drive is slowing down the system

[oshunluvr]

Seriously, the areas to look at are the bottlenecks: network speed tuning and file system performance are likely going to be the places you'll see the largest improvements. Video driver tuning might do a bit also, but mostly you're constrained by hardware when it comes to CPU and Video performance.

You could also install phoronix-test-suite and then compare your results at openbenchmarking.org and Phoronix.com.

Oops. Apparently reading comprehension is not my strong suit today

Unless this was mentiond before there is value in disabling systemd services which are not needed. I disable bluetooth, avahi, modem.

This is an awesome tutorial

I would also look at disabling systemd services that are not needed. For example I disable bluetooth, Avahi and modem services
