A few queries on KDE performance



Apologies if this is posted already - I couldn't find anything similar on a search.

We all come to Linux for different reasons, one of my highest priorities was to get a 'fast and light' OS for some old hardware. (Duron 800Mhz).

Having evaluated a full install of Slackware 10.2 for about 6 months I'm ready to reformat and install the system I actually want (conveniently Pat's just released Slackv11 - so I'll use that).

With regard to KDE - I must admit that it's impressive but it appears to be bloatware. It's packed with features and processes which I don't need nor understand and the overall effect is that it's pretty slow on my system in comparison to things like fluxbox.

Rather than exclude it from my new install I was wondering about the following:

- Can KDE be 'tweaked' to remove some of the ballast. For instance why does starting konqueror (even outside of kde, such is from flux or from flwm) start other processes like 'dcop'? Can this be removed so that when I want konqueror I only get konqueror, instead of konqueror plus several other processes?

- Can individual KDE apps be installed when the KDE environment is not installed (note: not just not running but not installed at all)? There are only 2 apps I've been even close to considering 'essential': konqueror and kpackage. I'd consider installing just those - but I don't know how much of the overall KDE framework they require. (I know that http://www.konqueror.org/faq/#CanIru...houtrunningKDE mentions qt, kdelibs and kdebase but I don't know how big they are. Is installing those effectively installing KDE anyway?).

PS: I know people can get protective. I'm not interested in starting a flame-war. This is a factual observation that KDE is a great package which appears unsuited for a small box. Help, education and constructive criticism are welcome, insults are not.

Thanks in advance,

Richard

I sure would be interested in Your success,
1.I would install slack without KDE and KDEI series and carefully search /var/log/packages for anything not needed,
2. install kde-base
3. fireup flux-box and start konqueror from rxvt and watch the error messages...
4. install up the packages containig the rest of the missing libs...

6. You won't get rid of dcop and mcop because it's the way KDE communicates amog processes (integration-data-excange etc) but wory not, kde is quite speedy these days, I still remeber kde2.4 and right now I'm on a 64MB&333MHz box running said Slack11 in KDE3.5.4, but Firefox seems to manage multiple tabs a way better than konq (thats tested I'm doing it as I type this<-).

7. Did you test emelfm? google for it or try to find your own. But if you need the POWER of konqi you'll have to stick to KDE and his *cop-s.

SCerovec; thanks for the advice. I'll try 1-4 when I get home tonight (sadly at work I'm stuck with XP, yuk!).

6: I was a faithful firefox devotee - but made the switch to Opera a few months ago. FF is great - I simply prefer Opera. I mentioned konqeror not because of web browsing, but because I need a file manager.

7: never heard of emelfm. If it's a good fast, stable, usable file manager then I may not need konq anyway.

Thanks again,

R.

emelfm

I'll take a while to evaluate emelfm but from what I've seen so far it looks good. For anyone else reading I also think tuxcommander looks interesting. Does anyone else have recommendations for a fast and light file manager? Or is there an existing thread with some good ideas?

Returning to the KDE/dcop issue. If a KDE app (e.g: konqueror) starts processes behind the scenes (e.g: dcop) am I at liberty to kill those processes without causing any problems? I'm particularly annoyed by processes (presumably daemons/servers) which persist after the main app exits. When I start an app, use it and then close the app I expect it to clean up EVERYTHING and not leave processes running which I did not request.

Thanks

R.

(After further thought I realised this might be better suited to 'Linux - Software'. Is it possible to move a thread to a different forum once it has started? I couldn't find an option to do so...)
