Raspberry Pi 3B Plus - speed test of ethernet, WiFi 2.4 GHz and 5 GHz through iperfPrint

The first article about Raspberry Pi 3B Plus described CPU benchmark, current consumption and also showed pictures from thermal imaging camera. Now, this article describes speed test of ethernet, WiFi 2.4 and 5 GHz.
The developers which are in touch with development of Raspberry Pi 3B+ declare the speed through ethernet up to 300 Mbps, but the ethernet connection is still through USB 2.0 converter. Is it real speed?
The Raspberry Pi 3B Plus board includes also WiFi module which supports 802.11 a/b/g/n/ac (2.4 and 5 GHz). What is the speed of WiFi?

Online C compiler and debugger - how to speed up the development of your C codePrint

I'm sure that you encountered with the situation when your code or part of your code didn't work as you wanted - operation with a few pointers, logic operations, conditions, parsing of value from long array etc.

If you have modern microcontrollers and development board which supports debugger (e.g. STM32 and Nucleo, Discovery) you can easily step (debug) your code in debugger.
If you don't have debugger, how do you follow values, variables? Are you using UART? Or LCD?
