Hi

We are about to restructure our server network and add a reverse proxy to
service requests to some 50 virtual apache servers.
Today we have about 100.000 page requests per day, of course not evenly
distributed over 24 hours.
We calculate with a increasement of 4 times within the coming 1-2 years.

We run Solaris 10 x86 on SUNs X2200 Opteron servers and I would like to
run Pound on the same type of server.

The backend is two servers running apache.

Does anyone have any recommendations on memory and CPU for running one
instance och Pount to serve this?
We will also use sticky sessions if that matters performancewise. There
are also two sites running SSL and we wish to terminate the SSL in Pound.

I have never tried Pound before but it looks promising for our needs.

Best regards, Stefan Linden

Hi Stefan, I can't comment on the traffic level, but we are running Pound on
very similar hardware; the previous generation Sun Fire V20z (dual opteron) and
the model up from your 2100's the X4100 - though we run x64 Linux rather than
Solaris. We're very happy with the performance.

Thanks for your reply!

Ok, that sounds promising, even though I don't know how many request you
serve per day (like you said).

Would you mind giving me a little mor info about you Pound server(s)?

Like, RAM, CPU and disks.

Best regards, Stefan Lindén

V20z: Dual processor Opteron 248's, 4Gb RAM, pair of mirrored 10krpm SCSI
disks.
X4100: Dual, twin-core Opteron 275's, 4Gb RAM, pair of mirrored 10krpm SAS
disks.

We're phasing the V20z's out in favour of the modular design and increased
redundancy of the new X-series servers. They have rather nice LOM facilities
too.

Currently have 100+ back-end systems defined (Zope, Apache, Turbogears etc..)
over 13 physical back-end web application servers (dual and quad opteron
systems), Pound is decrypting SSL for around 10 hosts. We shift maybe 250-300Gb
a month for all our web apps. It doesn't stress the hardware.

Hello Stefan and Jon.

I can comment on the traffic level :) If you are talking about 400.000 
pages a day, the configuration you suggested is more than enough. We are 
doing 1 mil pages and about 20 mil requests (images and styles and such) 
on a single core 3GHz Xeon with 2G RAM (we have two of them, for high 
availability, but the other one is just sitting there, doing nothing). 
Peak values come close to 500 requests/s. We run Linux 2.6 (RH4).

Jon and Michal, thank you very much!

Judging from you replies I think we are going to aim for the  
following hardware to start with and if we need more RAM we will  
upgrade that later.

X2100 M2 2.2Ghz, 1 GB RAM, RAID-1 80GB 7.2K RPM

Best regards, Stefan
