Sending a lot of osc messages (350 messages containing strings) in a for loop, seems to cause messages to drop (around message 250) Sending and receiving on the same host.
I use 1 worker.
If I add a delay of 500 nanoseconds (1 nanosecond didn't fixed it) between sending those messages, everything looks fine. Could be machine dependent (using CPU: Intel i3-2350M (4) @ 2.300GHz, on a older i7 machine I didn't notice this but might have missed it).
The problem seems to be on the sender side. Enlarging the buffer of scgolang/osc or enlarging the udp capacities in the OS or on the receiver side didn't help.
