Today we have published a new beta version of PRTG V6.2. Our developers have recently worked on PRTG's SNMP engine and optimized it heavily.
It can now query more SNMP values in less time and with less network load. Especially for installations with some hundred sensors or more (and for installations with small intervals, e.g. below 10 seconds) this new version requires less CPU load and causes less network traffic while showing better performance.
