Could you express this numbers in messages/sec? What do you exactly mean
with small and large packets? What kind of transport protocol are you
using? Is PD's implementation of OSC based on OSC-Kit?

The weak spot of OSC is parsing the address and descending the namespace
tree. Since with "small packets" you get a lower maximum rate, you could
have reached this limit.

I don't use PD but I'd like to understand how many messages this
implementation can dispatch per second.
