process optimization

chuck232 · 01-17-2005, 08:26 PM

After my random dealings with Mandrake, I feel I've gotten a pretty good handle on most things. However there's one thing I still haven't been able to figure out. I had my computer running once for probably about 20 hours on end. Over that time I had opened and closed a bunch of apps. I was just looking around and I found the KDE system monitor. I opened it up and to my horror, I had 2MB of RAM free. I looked through the processes table to see what was taking up so much and I saw about 15 instances of Konqueror. I thought this to be pretty weird as I didn't have any Konqeuror windows open. So I proceeded to kill all those processes. Then I opened up one Konqueror window. In the process table, it showed I had one open. Then I close Konqueror, but the process continued. No memory was free up and resources were still being used. Now is this normal or some kind of bug? I just find it kinda weird... Dunno if anyone else noticed this.

Do you have preload options on in KDE? ( Control Center->KDE Components->KDE Performance )

chuck232 · 01-17-2005, 09:06 PM

No, I don't have it enabled. Should I?

Konqueror didn't crash on you for any reason did it?

And its used by a few different programs.

Can you paste the lines from ps xww here?

Ok, I hope this is what you're looking for. This is after a restart:

Code:

And yeah yeah, I have a bunch of processes on that probably aren't used, but I haven't gotten a chance to fiddle with it yet. Don't want to break anything.

the memory isn't free because it is being used as disk cache. that's perfectly normal. It's what you should want actually.

sgrayban · 01-18-2005, 09:04 AM

Well I dont see 15 konqeror's running.

As for memory thats normal since linux uses all ram first then swap because ram is faster. If a program loads up and needs a higher priority then linux release memory that isnt being used for that program.

chuck232 · 01-18-2005, 09:13 AM

As I said, that was after a fresh restart and I hadn't opened up a bunch of Konquerors. If you want to see the process table with a bunch of konquerors I can do that too.

sgrayban · 01-18-2005, 09:25 AM

When it happens again then post but without the memory issue. Thats normal for linux.
