I'd like to ask is it normal CPU usage about 80-100% on system 4 cores/345hosts/5543DS (actually is 2GB RAM but could be more)?

Actually I have diffrent logs info about poller time:

More of template has 5min profile but Advanced Ping and Interface Traffic has 1min. In Poller settings is set Cron 5min/Pooler 1min.

It is possible that:
- every minute is starting Advanced Ping and Traffice Interface,
- ONLY every 5 min the other one?

If no, how can I improve cacti performance on this hardware?
