I just did a bit of a test. The laptop is a Dell 600m, 1.3ghz celeron, 512mb ram. Ubuntu 7.04 and XP are both pretty much virgin, although XP is carrying a wee bit of extra weight from a bunch of wireless config apps that I dont really need and keep forgetting to remove. Everything is timed from the button press that initiates the action, and stopped when the appropriate lights shut off (HD/Power).
Ubunutu 7.04
44 sec to login screen
26 sec from login to desktop HD light off
32 sec to hibernate
32 sec to restore from hibernate
11 sec to suspend
8 sec to restore from suspend
12 sec to load openoffice writer
With desktop + gaim loaded mem usage = 120mb.
With desktop + gaim + oowriter + oocalc + ooimpress + firefox + sysmon = 168mb
26 sec to shut down
XP SP2
24 sec to login
13 sec from login till desktop HD light off
9 sec to hibernate
13 sec to restore from hibernate
5 sec to suspend
5 sec to restore from suspend
4 sec to load office 2007
With desktop + trillian pro loaded mem usage = 190mb
With desktop + gaim + oowriter + oocalc + ooimpress + firefox + taskman = 234mb
19 sec to shut down
So yes, Ubuntu itself does use a bit less ram. The programs themselves however, use slightly more memory (+4mb), although these are all open with blank documents. But its nowhere near capacity in either case, so for my purposes (light office work) resource usage is not an issue in either case.
However, just about everything else I tested is faster - not slightly quicker, but 2-3 times quicker. I wouldnt expect pages to load or CPU usage to be much different between the two once the programs are loaded, but XP is really just that much snappier.
Not to mention battery life is at least 50% longer in actual usage on XP.
Linux is great for servers and all, where its light weight can shine, but I wouldnt use it on a desktop or laptop in the name of performance.
