I disabled it now. Last time I disabled this I noticed the biggest bottleneck was the port module. That takes about 85% of the total time.

Hi,
I tried the ramdisk. 48 Gb. I only have 64 Gb ram. It slowed down my system compared to the rrd's on disk. Maybe not enough memory left for all the other procs.
Then I added some more switches and my ramdisk wasn't big enough anymore. Now I have 280 switches/routers and 25000 ports a system load of 100+ and it's not making 1 cycle in 5 minutes. I tried 80,100 and 120 threads but when I get past the 80 threads the time to check one switch increases to much. Some routers take up to 200 seconds to check. I could setup a second system to check the routers...
A distributed option is a solution I think as I still need to add more switches.
Disable the fdb-table module globally.
