Interesting preso on Linux, showing Windows beating it in performance.

"Load Test Windows 2003 v Red Hat 4.0 (64 bit)"
...here are my summary from their slides:
"RAC Stress Test (150-250 users)
- MS Windows 16% more Transactions/Minute (TPM)
- response times up to 50% faster on Windows
- 250 users: Linux 30% of sorts on disk vs. sorts in memory
- Linux used 17%-40% more memory...
RAC User Load Tests (2500–4500 users)
- 3500 users, Windows 18% more TPM
- 4000 users, Windows TPM increased, Linux failed to complete
- 2500 users, response was 9%-33% faster on Windows
- Linux used 5%-25% more memory"
I didn't know Oracle was really getting into deciding which OS to prefer?

Solaris can improve your performance and Solaris gives you great features.
Sun really feels that Solaris has a strong lead over other operating
systems. We've shown various head-to-head comparisons on this blog. You
can see links to a few of those below.
It is also important to remember that Sun also has many important customers
who are running RedHat Linux, SuSE Linux, and Windows. So a variety of
benchmarks are also done with those, as you can see in last week's entry
on SPECjAppServer.
So expect to see results on a mix of operating systems as Sun fully
understands different customers have different needs. We still believe
most can get many benefits from moving to Solaris -- so if you are one
of those people who can switch, the evidence continues to mount that
it is a very good idea to use Solaris.

afternote:
I forgot to mention that Solaris is also Open:

...not something you see with IBM's AIX or HP/UX.

SunRay 2 desktop only draws 4 watts! The SunRay 2 desktop runs on shared server.
Typically we see a 10:1 – 50:1 SunRay to server ratio. Lets do some math.
ten SunRay2 desktops = 40watts plus Sun Fire T2000 at 330 watts gives you only
370 watts vs. ten PCs drawing 300 watts each is 3000 watts! The 10:1 ratio
is for heavier power users you can save even more if your apps can run at
even higher ratios of SunRays to Server. Even if you put power throttling
on your PCs because they are idle most of the time maybe you drop to 200
watts per PC or 2000watts for 10 PCs, still that is over 5.4x more power draw
for the PC 'solution'.
This gets PC out of the office (which takes the extra space-heater out of
your office), makes your office quiet, eliminates client upgrades cycles,
eliminates client version incompatibility, etc.
If most of your company doing email, blogs, browsing, desktop apps the SunRay
may be a great fit for you. The SunRay 2 can run Windows, Linux or Solaris desktop and works with standard monitor, keyboard, mouse.
...things to think about if you are serious about saving money.
