Hi, Is there any way of getting bigger speeds when sending small chunks of data (~50bytes)?
About my BBB: Rev: C. Kernel version: 3.8.13-bone70. Distribution: Debian. Scenario 1: looping big data chunks (4094 bytes): Baud rate set to 1500000 with: stty -F /dev/ttyO4 1500000. When I send (using write()) a buffer of 4094 bytes of data, and immediately after I read it (using read()), and count the number of loops for one second, I get around 160000 bytes (this means a throughput of ~1.3 Mbps). Scenario 2: looping smaller data chunks (68 bytes): Same baud rate, same method, I get around 30000 bytes in one second (~0.24 Mbps). How can I achieve bigger speeds when reading small data chunks? Is this test that I made relevant? (would be different if using another device that sends me data on UART (1500000 baud and aprox. 1.5 Mbps throughput)?)
