CPU is rarely the bottleneck nowadays, do here are some informal mem stats. Here, "memory use" is defined as the entry in the "used" column and the "-/+ buffers/cache:" row in the output of free -m. Note that I use my own custom Qemu VM image, so there is some overhead - in particular, it uses the KDE3 KDM. The KDE4 install was compiled with maximum debugging info, then all executables were stripped with objdump.

- X + KDM only (baseline): 34M
- Boot to default Plasma, with background (+wallpaper), panel, klipper, Kickoff and Clock: 76M
- As above, but with a Konsole open (2 tabs), very small KWord (alpha still!) document, very small kwrite document, and Konqueror with one tab open to dot.kde.org - 142MB.

So I think it's using slightly more than KDE3 at the moment (although if someone running KDE3 could repeat the experiment and give numbers, that would be great!), but considering the devs are mainly at the Make It Work/ Make it Work Well phase, rather than the Make it Work Fast (and Light), I think it's doing pretty OK. IIRC, KWord took up a big chunk of this, which comes as no surprise as it is still alpha.

So 512MB should be fine, I'd say :)

Thanks a lot for the info!
Looks like I'll have the chance to test kubuntu's packages :D

CPU is an issue for some people, e.g. the teams that refurbish old donated hardware with Linux and give it to the needy. (and no, I can't say I'm one of them) So it shouldn't be ignored.

CPU is an issue with my wife. She has a 750 Mhz Duron machine with 512 MB RAM. Now she is using KDE 3.5.8 and it's not fast but fast enough. I would like to put KDE 4 on her computer but, if it is much slower that 3.5 I won't change it over. I guess I'll stop upgrading her box before KDE 4 goes into Lenny (now I upgrade it with apt-get from time to time).

It's not that we are poor; we can afford to buy her a new computer but she wouldn't want to buy one when she's getting along just fine with what she has.

I think you shouldn't count on KDE 4.0 being as fast and optimized as 3.5.8. It will get better over time as things stabilize a bit, but I think the focus for 4.0 is on getting it to work, not on getting it to work fast.

Indeed. Note in particular that KDE3.0 was hardly a speed (or not-using-much-memory) demon when released, but steadily got lighter and lighter as time went on.
