Hmm... mind you...... on my dual core 2.6GHz-ish machine, with buntu 10.04, the load average is: 0.57, 0.50, 0.59 for a pretty much idle machine except firefox having a few tabs open.
I remember a single-core machine with a slower clock, less ram etc, about 4 years ago having an idle load of about 0.05, 0.01, 0.01. I'm sure this isn't a very good or scientific comparison, but I sometimes wonder if there is a problem with Linux.

My system is a dual AMD 64 Athlon 3.2GHz (I think) with 4GB ram and about 2.5 TB of internal disk. Running the default 10.04 kernal and gnome desktop. Used mainly as web and file server (24/7) and part time PVR (using kaffeine) as well as my main email and web browsing and development machine.
Clearly other people have issues with ubuntu 10.04 so maybe I'm just lucky.
I've got (quick count ....) six systems running xubuntu 10.04 or ubuntu server 10.04, I've not had performance problems on any of them really. There's a seventh system that also ran it without problems but is now sitting on the floor turned off.
The more powerful desktop systems all have 'on the motherboard' Intel graphics, except the older turned off one which has nVidia I think. No issues at all on any of these systems except occasionally some versions of VirtualBox hogged the processor, the current VirtualBox no longer seems to do this.
My wifes laptop is a Dell Vostro V13, single core Intel processor, that has no issues at all with xubuntu 10.04 and even runs VirtualBox quite happily.
The little Acer Revo runs as a headless server (for CUPS and DNS) with Ubuntu 10.04 server on it, I have a few GUI applications on it (synaptic in particular) which I run using my desktop machine as the X server. No performance issues at all, it's hardly lightning fast but perfectly acceptable for the jobs it does.
I have an Acer Aspire netbook (atom processor), mostly just for web browsing and ssh, it's quite happy with xubuntu 10.04, Firefox doesn't seem to cause it any problems.
Finally I have Ubuntu 10.04 server running on the eeePc which only has a 2Gb SSD, it's a tight squeeze (at installation I didn't add *anything to the base install) but again does all I need quite happily. The 2Gb is now 70% full with a full gcc/g++, configure, make, etc. development system installed on it (to build OWFS) and mutt (which pulled in quite a lot of other bits, such as postfix which I removed again).
OK, these are all xubuntu but there's not a big difference between xubuntu and ubuntu. I think it's KDE that can eat a lot of processor.
