Hello,
I forgot to mention that the current Netdot host is also housing a
cacti that is polling 84023 datasources and proccesing 42593 RRDs
every 5 minutes, it takes a bit more than 2 minutes to do that, so
half the time Netdot performance will be strangled by the disk I/O
being over the top. That should slow things up for sure, i probably
have the problems you point also, thanks for the advice, will look
into it.
I've already set up the new server, doing a updatedevices.pl -IFA on
an hp 2524 switch that took 1m57seconds on the old host, took 2
seconds in the new one :-)
Greetings,
Nico
