Slow upload PICO W

[GuillaumeLeclerc]

Hello,

I'm trying to upload a bunch of sensor data from a PICO W. I'm surprised by the low speed. iperf3 (C++) reports 1.1MB (which is less than what I hoped).

But when I repeatedly write to a socket 1KB with micropython I'm more around 160KB/s. Any idea how to achieve the highest throughput when using micropython ?
