Article: Linux versus Windows: OS impact on uptime and speed


http://blog.mon.itor.us//?p=286

From the article: ``There are many factors which affect Website 
availability and performance from end user perspective, namely ISP 
Internet connection, server location, server parameters, programming 
language, application architecture and implementation. One of the critical 
parameters is a selected Operational System (OS). Most users often need to 
select between Linux and Windows, two popular choices for web servers. By 
providing free monitoring service, we at mon.itor.us collected large 
amount of data to perform a unique analytical research examining OS 
correlation with uptime and performance.
...

Summarizing, statistically Linux based servers provide better availability 
and response speed than Windows servers. Absolute leader is NetBSD in both 
categories; OpenBSD and Solaris also demonstrate good results.

We hope this data will be valuable for our community in their hosting 
selection process.''

See the article for details, and enjoy!

ppcoea-renovation update (hackathon6)

This is a quick update of the branch status, as well as the results from the
hackathon.

1)  extr_intr unification.  Mostly done.
Prep and macppc have been converted to the new shared pic code.  Generic
handlers have been written for i8259, prepivr, and openpic.  Still remaining is
conversion of other ports.

2) clock.c. Done.  new one is in powerpc/clock.c.  Still need to convert more
ports over to using it.

3) shared pci code.  The code is in place, so far prep has converted.  Still
remaining is to convert the rest of the ports over.

4) Shared isa code.  Partially done.  It looks like we will have to implement a
scheme similar to the shared pci code.  Still need to solve a few problems
here, but the shared pic code gets rid of most of the isa dependencies that a
port had.

Even though the hackathon is officially over, the branch is still open, and
work continues.  Now that macppc and prep are mostly converted, these can serve
as examples to anyone wanting to try to take on a port.

LearN <at> BSD WWW changed name to P2O2's WWW

Hi,
LearN <at> BSD WWW changed name to P2O2's WWW.
New website embraced old Links page.

Direct address: http://pp.kv.net.pl/nbsd/index.html
If you find it useful I'll be glad.

Long live to Rexx! See the WWW why... ;-)

Cheers,

P2O2 Guide to NetBSD FTP

Hi,

I've made first preliminary version (0.5) of my "P2O2 Guide to NetBSD
FTP - understanding FTP levels":
http://pp.kv.net.pl/nbsd/ftp1.html

"NetBSD WWW Wrapper - P2O2's version of NetBSD WWW" is also ready:
http://pp.kv.net.pl/nbsd/index.html

Perhaps you'll find the pages useful. Of course, any remarks welcome.

Regards,

*My* favorite benchmark

We've seen a lot of semiscientific benchmark numbers thrown around
lately.  I happen to believe that the only benchmarks that matter are
properly written microbenchmarks whose correlation to architectural
features is well understood, and your own application.  And of course
benchmarks where you don't normalize everything you can about the system
under test are meaningless.

Microbenchmarks are boring.  My application is compiling operating systems,
because I do it many times a day for my job.

Here are results for compiling NetBSD 4 (checked out freshly from CVS as
of this afternoon) with GCC 4.1.2 as the host compiler for the NetBSD
toolchain, on two identical Mac Mini Core Duo machines with 512MB of RAM.

One machine is running NetBSD-current as of May 13; the other is running
FreeBSD 6.2RC2, because it's what I use as a host for building a
FreeBSD-based network device image at work.  Unfortunately that means I
will regretfully ignore any requests to run this test with other operating
systems or revisions; I don't have the hardware or time.

Both systems have the stock SMP kernels shipped with each OS's release
images.

Each machine has a single FFS filesystem, with soft dependencies, mounted
on /.  The NetBSD system has tmpfs mounted on /tmp; the FreeBSD system has
mfs.  Obviously, since both systems are stock Mac Minis from the dealer,
the disks are identical.

These are parallel builds (build.sh -j4) on a dual-core host.  I expected
FreeBSD 6 to win this test hands-down.  It *really* didn't -- since I do

Rexx in NetBSD

Hi,

I compiled ooRexx with GtkRxDlg in NetBSD. Then I've made rexx
scripts which helped me to build P2O2's WWW. You're warmly welcome to
come to my wensite and see the results. "P2O2's WWW" is in development
state but maybe some of you will find my rexx and bash scripts useful.

BTW. Is there anyone who use rexx for scripting?

Cheers,

Not anymore; long time ago when I was working for IBM.

   On the few occasions I use OS/2 nowadays, I do use Rexx. But I don't
see much point to use Rexx on my NetBSD system, since it has powerful
shell scripts, and when it can't do what I want, there's Python.

   Object Rexx is pretty cool, though.

Searching Localy *BSD FTPs' Application Indexes

Hi,
Some of you have two or three BSDs installed. I've written two scripts
to search all three *BSD application index files in a handy manner,
on your computer. And have the files in up-to-date state. Details: go
to my WWW or directly to the page:
http://pp.kv.net.pl/oorexx/makebsdindexes.html

As usual screenshots are provided. Have a fun.

Regards,
