Loop back timings

Does anyone known the time in loop back configuration with 115200 kb with 10 byte ?

I found around 20ms using different softwares, I hope It could do better …

Thanks.

Digi gives some general timing characteristics on the knowledgebase article listed here:

As you can see, 1 byte in loopback is approximately 8ms, while a 32 byte packet is approximately 16ms.
