Where r00t has no land

So here are a few settings I used to have my cactid work without producing any gaps (I had this issue on my system, where allot of gaps started appearing on my graphs, and additionaly the polling performance was low).
My system specs:

Intel(R) Pentium(R) 4 CPU 3.00GHz
512Mb memory
73GB HD

I used the following poller settings in cacti console go to:

Console --> Settings --> Poller

Maximum Concurrent Poller Processes: 4
The Maximum SNMP OID's Per SNMP Request: 8

My cacti monitors: 123 devices with 3110 data sources.
