Okay, so I have to wait till this is patched in spine?!
At the end of the "run" I can see the poller.php working hard,
and two spine processes are running.
Any hints how to get out which script took as much time?

Betreff: [MASSMAIL]Re: [cacti-user] Performance

The "weight" is determinded by counting datasources. Each datasource is counted as "1".
In case of a "pure SNMP only" system, this might be a quite good approach. But it is clear, that runtime of e.g. scripts will cause quite different runtimes of spine processes. And this is obviously what you see.
To do better, this would need a per-datasource runtime counter instead of "1".
Patches against spine to implement this are appreciated.
