I was the one who messed around with RAM disks and while they provided some improvement...it didn't seem to last long doing the only method I got working (which was make a tmpfs rsync/cp stuff onto it and then symlink/overlayfs that tmpfs) plus it seemed everyone was saying it was wasting reads on the SSD. I tried to get a block level ram cache setup but failed to get that working as I actually erased the drive I was trying to do that with even though I followed the directions I think well(rdxdisk I think it was called). Seems vmtouch is also a bust as I'm not sure why sometimes the things I think I'm getting to link speed up and other times don't. I'd need more time than I have (2 big papers/projects due this week) to truly test it out and I'm again not sure I'm the right guy for it...I'm actually hoping someone else would either have tried something similar or have a go at it and give a review. I also think I might be trying to use it for something it wasn't intended as sometimes I can't get folders with libs or libs themselves to lock without invoking sudo redface.gif.

PS: I'm starting to think it's the mismatched RAM since my laptop is faster (well outside of games). I've also recently switched from discard to manual fstrim (haven't done a TRIM yet as I've got more than half the space empty and haven't done anything heavy like game or anything).

Do you ever go through your logs to see if you're getting errors?

Was wondering what specific programs and with these programs that you are running, what specifically is slow? IOPS? Load times? Throughput?

If it was something like a java app or server (or other programs support it), then using large pages can often greatly increase performance as large pages use fewer TLB lookups and the memory cannot be paged or swaped and therefore is always available.

You can sometimes mess with blockdev to help disk I/O as well.

Right now my targets are XBMC, Chrome, Libreoffice, PlayonLinux(and by extension MSOffice). Those are the big ones where my laptop has an edge that bothers me. I'm sure I don't understand enough about computers but the ultimate dream would be to have control where I can direct that certain programs(and probably libs needed by them) are just ready by default. IE I can say load and keep these things in the cache at all times. So I'm basically just trying to get the things an end user notices (load times, and I guess responsiveness though I think that's another issue) as fast as I can for now. redface.gif

What does your memory usage look like? Can you run vmstat?

Turn off desktop compositing. Then test out the responsiveness. If it's better, then change KDE's rendering to low quality.

Anything that errors and/or looks odd. If we knew the error before hand, we wouldn't need logs in the first place tongue.gif

XBMC is never going to be quick to load because you have a zillion processes to go through before the GUI is even usable (scan for all the config directories for plugins, read the other config files, import your SQLite database, launch Python interpreter and execute all your plug ins, scan your media directories for changed files, load all your resource files like images and navigation sounds, fetch the latest RSS feeds, etc)

Chrome can have similar issues if you're running several extensions.

So your issue with those two are not access times, it's just a matter of raw CPU grunt.


I'm not familiar with PlayOnLinux. Is that a WINE thing?

PlayoinLinux is a gui front end for Wine. It has quite a bit of stuff prebuilt like MS Office. Think crossover on the cheap in looks and function.

Or we could just use something open and cross platform like LibreOffice and not have the abstraction of emulation thumb.gif

Granted it does have some compatibility issues with some of the office stuff....especially as Microsoft keeps changing the format and making it harder to reproduce so they can lock you into their product. Hate vendor lock in

WINE is not emulation.

And if you read Rookies post he also mentioned LibreOffice.
