Until you try to do something... Benchmark the time to create a new
process on windows vs.about anything else, or the time wasted
in context switching among them.
By far the slowest machine/OS combination I have is Linux (FC2) on
my fastest (2.7GHz) machine. Windows XP on that same machine is
noticeably faster (not just measurably faster).
As an example, I just "right clicked" on my desktop, and it took
five (5) seconds for the menu to pop up. Selecting "open terminal"
took ten (10) seconds before first prompt. I have no unusual scripts
which run at terminal startup. Windows XP is much faster in starting
a console window.
I just opened Open Office "Writer Word Processor", and it took
thirty nine (39) seconds to initialize.
You are observing disk access time and window creation time,
next to nothing to do with CPU time. For a similarly
'look and feel' approach to process creation time, run something
like '/bin/echo test' on a virtual console and time it on the 2nd
run when the program will be in the disk cache.
I am aware of what I am measuring. Thanks for the reply.
My original point stands. Windows is not a cycle hog. Also, my
second point stands. As far as "until you try to do something",
Word starts much faster on my machine than does Open Office.
So do many other apps, like my web browsers. I think this
qualifies as "creating a new process".

Not trying to start a flame war here, but I think your box may have a
problem. I can start open office writer (1st time, not cached) in 15
seconds on my 933 Hhz PIII, 512 MB crap box. Of course, 15 seconds is
way too long! Right clicking the desktop produces an menu in less than 1
second. You need to find out what's consuming excessive CPU or memory,
since the bad performance you're seeing is not normal.
I agree with you that XP does seem more responsive than Linux, for most
desktop applications. They've done a lot of work to improve this aspect
of their software. I still won't ever install it on any box that I own!
I've never *installed* Windows on any machine I own. This box (2.7GHz
HP/Compaq Presario) I bought with Windows XP "pre-installed". I re-
partitioned and put Linux as an alternate boot. Actually, I almost never
do boot Windows. I do have Windows on three machines I own (2x Win98,
1x WinXP). The machine I use most except for this one runs MSDOS 6.0
w/o any version of Windows.
I've certainly installed and run Windows on other people's machines.

I can explain it for you, but I can't understand it for you.
I speak only for myself, and I am unanimous in that!
