300ms ! Is your PIC on another planet ? :) Just a joke...

In order to test performances and reliability, have you tried to ping flood
your PIC ?

$ ping -f 192.168.2.3

According to man, ping sends a ICMP request each 200ms. ping -f (requires
root privileges) will flood PIC with requests. If you start to see dots,
this means PICs can't handle all requests. In the end, you'll have % loss
packets.


Cheers,
Seb
