Question Memory Optimizations ?


Hello All,

I have noticed that Linux tends to use ram quite well (lots of caching... not much swapping) however, there are certain programs I run which wind up in swap all the time.

The only time they don't wind up in swap is after linux has finished some kind of internal memory clean up... my hd chatters for a while, and any swap usage disappears, and overall mem usage falls.

I was wondering if I can run that program manually, at will... or whether there is a good 3rd party program that cleans ram under Linux...

Cheers,

-TJM

I don't know, but I am going to watch this thread to find out. I was also curious, what process do you follow to determine which programs are in cache and which are in ram? I have been wondering how to tell this.

Thanks,

PhilD

Dont worry about it, theres no programs because Linux has excellent memory management.


Some programs always go into swap because that info is "unimportant" or not critical. Important stuff goes into RAM, secondary stuff goes into Swap. Its not really about the RAM being full (though that CAN do it as well, but most likely not. ).

So, don't worry about it.

i think...programs will go into SWAP
(1) if they exceed RAM
(2) unused part of the program will go to SWAP.
is it correct.??
if so...then in either case its not a bad thing to happen.
