Yes, site based on Drupal 7. I trying to switch off drupal cache, all the same.

When I add a new parameter (http://site/?qqq), page generate long time. When a request a page with the same parameter again, page return fast. When I change parameter again, page generate long time again.

This is some sort of information portal, during page render scripts make about 50-75 requests to db.

Yes, mysql 5 on anotner VM (in the proxmox virtual local network).

No, filesystem is not using (during start page generation, which I use for this tests).

I run tests via httperf (and now for single requests trying simple wget).
All machines is VM under proxmox with 512mb RAM and 1 virtual core, except nginx+php server - there is 1 Gb.
Dictinct VMs for nginx+php, db, and machine for test running. Also there is one proxy/load balancer machine, but now balancer have 1 node in config and redirect all requests to nginx (proxy using nginx too). I trying to exclude proxy totally (with direct access to nginx+php server - all the same).

This is VM - proxy, but I trying to exclude it and make direct requests to nginx+php machine, this has no effect.
