As a imperative and always mult functioning user, doing everything at the same time, for me is a necessity to utilize as most as possible of my Random Access Memory. Despite the fact that I'm using Slackware linux, which was supposed to don't drag out too much of the memory, I can't get the expected efficient and the system usually freeze. That's because I only have 4 gb of ram.

So I'd like to know some tips to let my system faster and clear. Mayb e any scripts. Don't tell me to shut down things that are not used or things initialized with the computer 'cause I've aready did that.

i have 4GB and no problems

use ublock ?

vm.swappiness=10
zram + zswap

When the system become unresponsive it can be because the lack of RAM makes it use swap instead, but also (and more likely) because some process consumes a lot of CPU cycles.

The "free" command will tell you if the swap is in use, then "top" or "htop" will allow you to find the offending process and possibly kill it. See the man pages for these commands.

This phenomenon can happen on any Linux distribution as it's usually due to some running application, rather than to the distribution itself.

I actually use 2.4 gb of swapp, and there's a script running with the function of drop caches and allocated memory if the ram usage reach 80% every hour.

Look into ulimit. Here's an old SlackWiki article to start you off.

Also, running a 32-bit distribution and not a 64-bit one helps.

Still, as long as you don't investigate what fills your RAM (if that's actually the case) or what eats all you CPU cycles (if that's actually the case), you won't solve your problem. Solving a problem needs to know the cause of the issue and for that you need to investigate, else you are like a medical doctor who gives medicines to his patients without having made a diagnose. Would you like to be treated for hay fever if you if you have pneumonia?

What type of drive holds your swap partition(s)?

If it's a slow drive, you'll get a pause when whatever is stored there is swapped back into RAM. If you actually *are* using 2.4G of swap (versus having that much allocated), then you can get some long pauses.

One way to see what's going on (that's included with Slackware) is GKrellM.

Open a terminal, start it with
You can close the terminal window and GKrellM will keep running.

You'll get a graphic "stick" that shows your CPUs, Procs, Disk, Eth0, ppp0, Memory, Swap and up time.

Grab it and move it over to the right side of the screen where you can see it.

Your CPUs should display right about 0 - 1% use when the system is just sitting there mumbling to itself (with Firefox and Thunderbird running, for example), you should have something like 512 processes, disk should be pretty much nothing, eth0 about nothing, memory and swap about nothing.

If the CPus are at more than 50%, you need to find (using the tools recommended by others above) what's doing that: what's running and why is the question. The Mem and Swap displays are a horizontal ruler type display and they should rarely being doing much of anything.

Keep in mind that a quiescent system (even with X and a couple of applications running) isn't doing much. There are a lot of processes started but they're mostly interrupt driven and just sit there waiting for something to trigger them. Things like Firefox and Thunderbird don't do much most of the time (typing this doesn't cause any bumps in the fields).

If you've got an application that is either poorly designed or is a huge memory hog (which indicates a poor design too) and that drives the CPUs to 90% or more, might be time to look carefully at that application, eh?

Hope this helps some.
