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.
I am using Ubuntu 10.04, default kernel, default Gnome, on a single core machine (Pentium 4 3GHz), and almost all my load issues are caused by Firefox! I have one tab open to write this email and the load average is about 0.18. Meanwhile in top the other big CPU users over the past 6 days uptime are "beam.smp" (part of couch db, part of gwibber, which is pants because it breaks when I sleep or hibernate the computer) and Xorg.
I am also using ubuntu 10.04 since June this year. I didn't have the upgrade problems from my previous o/s (Kubuntu 8.04 32bit) as I did a clean install to the 64 bit 10.04.
I have a nvidia card that works ok but the system reports "no proprietary drivers in use".
top reports: 09:49:33 up 11 days, 20:28, 2 users, load average: 0.19, 0.34, 0.31 Tasks: 213 total, 1 running, 212 sleeping, 0 stopped, 0 zombie Cpu(s): 3.8%us, 0.7%sy, 0.0%ni, 95.4%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st Mem: 3350264k total, 2881072k used, 469192k free, 465348k buffers Swap: 1124508k total, 6260k used, 1118248k free, 1385244k cached
Although I admit to not knowing what load average is or most of the other numbers! Although I really must increase the size of my swap.
The only real performance issue I've had was running some f-photo which after a few hours had taken 100% of the memory and 100% of the swap. Other processes then started to die. That was my last re-boot. Otherwise it just chugs away 24/7. Of course I have nothing to compare it to but I feel it is much faster than Kubuntu 8.04 which I had put down to now running a 64bit o/s.
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 upgraded one of the laptops about a fortnight ago to 10.10. Seems OK so far.
Hope this helps somebody.
