You could also try to set
wlan.config(pm = network.WLAN.PM_PERFORMANCE)
but this does not have too much impact.
With a 500ms delay on host between packet send , there are average 75ms turnaround.
Not clear where the delay is originated. Could be inside pico, but also my WIFI setup or somewhere on the host. ARP cache timeout, perhaps.

send-receive UDP, 800 bytes, 2000 repeat. 500ms delay between each cycle. Diagram shows turnaround times in second, number of occurrence in a histogram. y-scale is logarithmic.
