This article covers the contents of the author's test by connecting the AE-ESP-WROOM-32 module and the W5500 module USR-ES1 to check and compare the performance to use Ethernet.
The author used the ethernet2 library and covers the SPI connection method in detail.
The speed didn't come out well when tested with the default options, but the process of changing the SPI clock frequency and changing the library's SPI transmission method to burst to more than triple the speed is impressive.
In the summary of the article, we can see that the test results were good, so author decided to use the Ethernet function.
