I cannot give any performance data for Cacti at OpenBSD since i'm running Cacti at FreeBSD 7.0.

At the beginning a had mostly problems with mysql (open connections), until i set the wait_timeout parameter to the following value.

file: my.cnf
Code:
[mysqld]
max_connections=1000
wait_timeout=900
With the standart Cacti (php) Poller I was not able to process more then 120 DataSources without timeouts ...
A real boost comes from cacti-spine.
With spine I can process now 600+ DataSources and 330+ RRD's in ~5 sec. (network switches + some hosts)
Code:

 Cron Int: '300', Time Since Last: '301', Max Runtime '298', Poller Runs: '1'
