Deprecated - Performance and scalability

I have read some articles about performance and scalability of Drupal sites, but i can't find anything that is especific on PostgreSQL data base system. I'm very interesting to know what will happen with my site when the amount of data stored in the DB get a considerable big increase in a few years, i'm sure it will. The site i'm talking about is using abaut 50 modules, the acces on it is not high, the hosting servers (DB and web) are not the great, but adecuate. Like i said, my concern is the growing of the amount of data stored.
Thanks.

Hi,

I was wondering, what is the best way to host multiple drupal sites on the one server using different themes, different databases and different directories. At the moment, I have multiple Drupal installations running with separate databases, in separate directory locations. They run off the same domain name from a folder that is appended to the domain name.

Any help would be great.

Thanks,

Sarah

Does anybody have an idea how I could create a user forum that is as fast and snippy as this one?:

What do I have to focus on? Thanks for your help!

Hi,

I am running drupal 5.7 behind a reverse proxy and every entry on my log is registered as coming from the proxy, drupal is not getting the "x_forwarded_for " values in the http traffic.

I have found that drupal6 allready works ok behind reverse proxy but I haven´t found any way to make it work on drupal5.

¿is there any way to do it?

many thanks in advance.

I am trying to share user information across multiple sub-domains and came across this very good URL which explains how to achieve that using db_prefix.

http://drupal.org/node/201673

I am using V6.x and the way I started was that, I shared only users, users_roles and sessions tables across the domains, since I want every thing else to be different across sub domains.

Im having problems with one Drupal based site. My hosting company calls me and tells me that my application is using too much memory and CPU resources. I´m not using too much modules, just core and basics like CCK, Views... The configuration is ok, the caching is on and css compacting too.

I changed the caching time to get a better performance. What more i can do to optimize the CPU and RAM using?

Thanks
