Hello, The requested sizes do change a little during the initialization. Also the settings are not persistent across reboots of your host computer so need to be re-appled each time you restart or changes made to other configuration files to make them persistent.
Can you confirm which sizes you are using in your commands at the moment? For each of the read and write settings you should use the largest size listed, no warnings should be displayed after that. You can try running benchmark_rate which is a C++ program to test if this is a Python specific issue or just a settings problem.
