SuSE Pro - Mem leak?


Not sure if I have a Memory leak, but top reports high mem usage even when idle:

I am running SuSE 9.1 Pro, Updated as of today, DMA is on. Overall, system seems sluggish. When running Personal Edition, system worked great (this is a clean Pro install).





Please advise.[QUOTE]

Just tried fluxbox, and the system seems to have the same issues?

Any ideas? Anyone?

I wouldn't consider this a memory issue until your swap starts thrashing.
I suggest you search the board for other memory issues, you'll find that linux manages memory somewhat differently than you may be used to. I don't think this is the source for your sluggesh system performance.

Take a look at the total number of processes being run on your machine.
a few useful commands:
Code:
ps -aux |wc -l
[total number of processes]

ps -aux | less[lists the currently running processes in the less pager]

Thanks for the reply Shade.

When I ran the command you suggessted, the output seem to display process and their mem allocation. Just a rough estimate, it did not total my system RAM.

I can post my actual results when i get home.

Just ordered 512MB of RAM to drop into my system. If this doesn't boost performance, I don't know what I can do....

Well, I've ruled out a possible leak. I'm thinking it could be that the Pro version is Robust, and uses Mem to the max.



Hopefully my new RAM will help.
