What is the minimum latency we can achieve in Xbee SX Pro Module

Hello all,
I am using XBee SX Pro with a baudrate of 115200. I want to know what is the minimum network latency I can have if I am sending a data of 19 Bytes over Xbee?

I would suggest looking at https://www.digi.com/support/knowledge-base/timing-comparison-for-data-transfer-by-product
