I ran the attached demo (basic web server) on both a MKR1010 and MKR4000 board.
On the MKR1010, the demo is functional as to say, the web page is served and rendered fast enough but on the MKR4000, it takes ages to render the page !
It seems the MKR4000 board is running much slower than the MKR1010 !? Why ?
Is the M0 running at a lower clock speed ?
The SPI communication goes thru the FPGA according the schematics, not directly from the MCU to the uBlox Wifi module as on the MKR1010.
Any ideas welcome !
