Hi !

I have the following problem . i 've installed kdemod3-base (the minimum edition) and when i boot the ram usage is about 300 mb ram . After a while , after using ktorrent or firefox my ram goes up to 950 mb and i have only 1 gb ram . this is what i get with ony konqueror open :

free -m
             total       used       free     shared    buffers     cached
Mem:          1010        944         66          0         12        809
-/+ buffers/cache:        121        888
Swap:          972          0        972


does anyone know what might be the issue ?

Re: [SOLVED] high ram usage

Hey

The 944 MB include the RAM that's used by the kernel for caches and buffers, it is made available to programs as soon as they need more.
The actual amount needed by your running programs is in the second line: 121 MB

Re: [SOLVED] high ram usage

I hope you know that RAM is faster that HDD, so if you have a Ferrari (RAM) and a biiiig truck (HDD) and you want to drive really fast, which one will you pick? Sure, the truck can hold a ton (or rather several tons) of things, but it's not a speed daemon. If you have the Ferrari just standing in your driveway all day long you're not really using it right, right? On the other hand, if you use your sports car for everything but the toughest jobs (which require the truck), you can feel the performance you payed for - that's the cache thing.

No offense, but maybe sb knows if there's such a thing as manpages for dummies? ;-)

Re: [SOLVED] high ram usage

As fantastico said, your system is actually only using 121mb of RAM. The rest of the "used" RAM is cached with will be released for other programs if they need it (for programs not in the cache), or reused (for the programs that are in the cache).

At the end of the day, even if this wasn't the case, I wouldn't be so worried. Don't you *want* your RAM to be used? Free RAM is wasted RAM (and money). If you're not going to use it, why bother having it installed in your system?
