 Posted: Sat Aug 05, 2006 6:24 pm Post subject: memory usage question |
 |
|
I upgraded my memory from 512mb (333mhz) to 1gb (400mhz).
Before i upgraded i checked memory usage of the following command: | Code: | | mencoder -ovc raw -oac pcm -o /dev/null myfilm.avi |
. Since it's a heavy task cpu usage was about 95. It used 490mb memory. After upgrading i got about 985mb memory usage for the same command.
Another weird thing is that now i have only kopete opened, few shells and browser and i have 980mb usage. cpu usage 0.3%
Why is that? How can i repair it? |

No need to worry - the free memory is filled up with file buffers and stuff. When the programs request more memory, it will be allocated as usual. So, you shouldn't take 'free memory' into consideration. This memory, which is used for buffers, although not being shown as free memory, is effectively free for apllications' use.
Your application, taking 900+ MBs of memory, is I think due to the way it's programmed, i.e it hogs all the memory it can. Or it might be a memoy leak/bad proramming in application code. |

Thank you. 
The command checks integrity of an avi file and decodes both audio and video. Indeed, it can be a memory leak. Will ask the developers of mplayer. |
