[users@httpd] apache in big sites
Hi, can somebody answer this questions please?
Dou you know which big sites use apache? yahoo? amazon?
Do you know number of dinamic pages per second that an apache web server
of a big site can answer? Do you know the hardware configuration of a
big site server (memory , number of processors)?
Do you know where else can I find this kind of information? (performance
and scalability in a huge server with 10 processors and 10GB Memory)
I thank you very much in advance,
Luis

What OS and platform are you planning to use. Usually it is the function
of the SMP capable OS to distribute processes/thread to the CPUs.
Have you looked into the option of having a cluster environment of the
quad/dual HYPERthreading CPUs, instead of 1 server with 12 processors?
I having tried HYPERthreading CPUs with SMP Linux Kernel and Apache 2.x.
Works quite well. But I have not tried 12 processors systems.

Thank you very much friends, It seems (based in your experience ) apache
can scale in a huge machine on connections, processor use, etc. Maybe
the machine is too big that can fullfill the network before it uses all
the resources.
What I need now is some numbers, I will search in yahoo about benchmarks
, and then I will make some tests-> then I will tell you the results.
My apache is 2.x and has MPM worker configured, the hardware is HP.
Luis.

Yes.

Apache will support as many connections as the operating system allows.

Not on 12 CPUs, but on 4, and I'm sure many others have as well.

Long before you use all 12 processors, you're going to saturate your
network connection and/or your disk drives. You'll probably do much
better purchasing expensive disks and/or multiple servers each with
a dedicated network connection.
Apache is not a CPU intensive process, I don't know for sure, but I
wouldn't be surprised if a single-processor machine is capable of
saturating a 100mb/s network connection with ease. Disk speed,
network performance and RAM (for caching files from disk) is going
to be more important than CPU speed.
Do some google searches on +benchmark +apache to see what kind of
actual stats others have gotten.

http://httpd.apache.org/docs-2.0/mpm.html
Wether Apache uses all the processors or not is up to the operating
system.
Apache either uses multiple threads or spawns multiple processes
(depending on the mpm module used) to handle the connections. How
those threads/processes are distributed between the processors
depends on the OS.

Yes, I agree with you, but what I would like to know is if apache can
scale on a server for example of 12 processors and 3Gb memory.
Will it support more incomming connections? Will it use all the
processors? the performance will grow a lot or not? Have somebody tried
apache on a machine like that?
I know there are lots of condicions to measure the performance of such a
system, but I only want to have an idea of how would be the apache's
behavior in a machine like that.
Thank you Saqib.

This is a very subjective question. Depending on your server
layout/load-balacing/clustering and most importantly your application, you
will get different results.
I give will give you a quick example:
Let us say you have application that requires https:// (SSL). You can have
a single processor server using Hardware SSL acceleration (e.g. nCipher's
CHIL) give you a better performance than a quad processor server that
DOES NOT have harware based SSL acceleration. And even this answer is very
subjective.
Apache can optimized to achieve extermely good performance.
There are some vendors that provide commercial support for Apache:
1) Covalent
2) StrongHold from RedHat.... based on Apache???

Just a note:
The really big sites don't use *one* server. They use a *bunch* of
web servers and balances the load between them
