AFAIK, cacti uses the php interface to net-snmp libs in their poller code, so they are a bit slower. For that they made another poller in C just for performance.

Stacy, all tests planned will be on the LAN only. No incoming bandwidth will be used (not that I have the kind of bandwidth that would stress the servers anyway ;) Anyway, as Mike said, we will of course be co-ordinating with you.

Anyway, please let's dont let the thread slip into a Zabbix-vs-Cacti debate, since it's difficult to get a chance to stress test the servers, I hope to get all relevant information the first time. Kindly, do let me know your suggestions regarding:
- Test setup/conditions
- Interesting apache configuration options we might need to test under (currently no config sweeping is planned)
- A kind of load monitoring tool we could/should use (other than "top")

Best Regards
