I poll 20 devices with 66 data sources.
My crontab runs poller (cmd.php) every minute. All steps are defined as 60s in cacti.The CPU load of my server climbs to nearly 100%, and free memory is 0MB.
If i define polling every 5 min in the crontab, things looks OK (CPU 40%).
I've defined "Maximum Concurrent Poller Processes" = 3 but it appears there is no effect of the performance of the server.

Thanks for your help.
When i run manually poller.php, rrdtool process lives during 1 min 45s.
Does it mean that polling is not finished in 1 min ????
What is difference between cactid and cmp.php ??
I can't see cactid nowhere in cacti directory.
If your polling interval is 60 seconds and you aren't completing your polling in 60 seconds or less, you will have problems. Which is more than apparent right now.
Move to cactid, it should help the situation. Problem is, as soon as you move forward with adding more hosts, you maybe in the same situation.

I assumed you where already doing 1 minute intervals.
If that is the case, you need to alter your settings to use cactid. Paths and Poller are the tabs of intrest.

So, i had modify the line in the crontab, and replace call to "poller.php" by call to "cactid" ???
Have i to run cactid "manually" for the first time ??
I've already altered configuration in cacti, by defining cactid as polling method, and define path to cactid binary file.
Poller.php calls what ever collector you select in your cacti settings.
Put poller.php back and got look at your cacti settings in the web interface.

Re !
I've installed cactid. It is running an graphs are generated.
I've defined 10 threads for polling process.
The problem of performance is already .... a problem.
Always more than 90% of CPU load and full memory used.
Is rony already woken up ????
