Deprecated - Performance and scalability

Long time drupal user, first time poster.

I'm running a drupal site that's been getting more than 50,000 queries an hour and as a result the site host (it's a shared server plan) yanks my ability to access the database until the queries clear out after a few hours. I've used the database user array work around and that worked for a while but now it maxed out two of the three users already.

More details that could help: It's an entirely private site so caching isn't helping out. There's approximately 100 users (only about 25 active at anytime) and about 1400 nodes.

We at Zend are looking to do some benchmarking of Drupal and the Zend Platform to gauge performance improvement as a result of the code acceleration and content caching modules. If anyone has any actual or anecdotal benchmarking results we'd be pleased to hear about it.

If you'd be interested in helping us out on this project we can supply an extended evaluation license of the Zend Platform for testing purposes.

hi im very new to Drupal and also Php. I have a Drupal 5.2 site on my system using Wamp 1.7.2. Every time i click the Administer link i get this error:

Fatal error: Allowed memory size of 8388608 bytes exhausted (tried to allocate 24576 bytes) in C:\wamp\www\drupal\modules\system\system.install on line 1478

I can get in the Administer area by clicking other links but i get same errors if i try to install modules. Im not sure if Wamp is causing this or Drupal. Any ideas?

IN order to have just one "create content" link ie either story, blog or image ( or a replacement word for them) i was wondering what the difference between a module that provides images and content and one others that do not?

thanks

why would someone want to use the image module if they have tinymce etc at their disposal?

I'm putting Drupal onto a high traffic site and I'm concerned with the scalability of the anonymous sessions. I asked about disabling the sessions in #drupal on freenode and there was interest in the solution, but no one had done it before, so I'm bringing the question here.
