Re: high memory usage in KDE?
Hi, One thing to keep in mind is that linux caches a lot of code and data. Thus memory will probably be used by applications that are not running. You will notice this effect when an application starts up faster the second time than the first time... So Linux will try and keep your memory free as low as possible as what good is memory that just sits there doing nothing. As far as I understand it kdeinit is kind of a launcher of most kde apps. So if you run something like konsole, it will show as kdeinit: konsole... Now you might have a lot of fun with your audio apps as noatun seems to eat memory, especially if you are playing a movie. I myself do not like this very much and though I also think KDE uses a lot of memory I have kind of made peace with it. Think about it this way: Windows eats memory right? Now what we expect is for KDE to be a windows replacement, we want drag and drop, we want applets on the panel, kparts, and all other nifty things (me myself want to run konsole as much as possible). Doesn't it make sense that as we add more features KDE will eat more memory too? This will be the trend in future and the only thing we can hope is that it will crash less than its counterpart...

IIRC, Linux allocates a lot of memory for the disk buffer, so it's not only the applications that cause the high memory consumption. Anyway, I would recommend icewm if you're looking for a window manager that is less hungry concerning memory. Regards, Niklas -- Not everything worth doing is worth doing well.

I cannot comment on the gnome part, or the 10 instances beeing required, but you have been fooled by the top program, most likely. Most programs will share memory. Especially true for kde-programs. Quoting the top manpage: RSS The total amount of physical memory used by the task, in kilo-bytes, is shown here. For ELF processes used library pages are counted here, for a.out processes not. SHARE The amount of shared memory used by the task is shown in this column. Also note that Xfree86's memory usage is counted multiple times/shared. I honestly don't know how to create more clear mem-usage statistics, but have a look at free -m (the second line of values count: -/+ buffers/cache) If someone has other suggestions, I'd love to hear from them :) I've been fooled by this myself (my wmbubblemon duck died multiple deaths from drowning, even tough I run the lightweight wmaker :) -- Greetings Joris [EMAIL PROTECTED] UIN: 25569167 PGP is currently out-of-use

Note "window manager" is exactly that -- the thing which draws borders around windows and helps you interact with them. You can run pretty much any wm you want and still use KDE/GNOME apps. Some wms interoperate better though. As an experiment load up just a window manager and run the KDE app(s) you are most interested in. I use blackbox on my laptop and run one or two kde apps, mostly konqueror. > one last thing - one process in particular seems to take the most memory, > which is kdeinit. using 'top', i see about ten instances of kdeinit, each > using about 5-8% memory. i assume this is part of the kde desktop, but > should there be so many instances of it? > sorry, someone more familiar with running the full KDE suite will have to comment on this. What you might be seeing is a threaded application which ps shows as multiple instances of the same app.
