Hi, 6749 targets is a lot. Have a look at http://lists.ee.ethz.ch/smokeping-users/msg01728.html It basically says that the measurement time is around 20 milliseconds / host / ping, which seems apply to your situation as well. I don't think reducing mininterval below DEFAULT_SELECT_TIMEOUT compiled into fping (10 milliseconds by default) helps anything. I don't know how small timeouts select(2) can handle, but you could try lowering DEFAULT_SELECT_TIMEOUT and recompile. The other recommendations in the above link apply as well: consider splitting the probing between multiple servers, possibly with the Smokeping '--filter' option, or define two FPing probes and split the load between them.
