Beta-IDE too slow

winnepa · July 9, 2021, 2:05pm

Hey, the use of the beta IDE for ESP32 DevKit is approx. 3 ... 5 times slower for compiling and uploading than the IDE 1.8.13. Is not an improvement on 1.8.13. What can I do?

I believe the problem is not the true speed of the compilation and uploading, but rather the throughput of the console pane to print the output from the compilation and uploading processes.

There seems to be a horrible bottleneck somewhere in the data pipeline between the compilation and upload tools and the IDE's console, which I reported here:

## Describe the bug 🐛 The rate of the output from the upload tool shown when …verbose upload output is enabled in the preferences is very slow. There seems to be some significant bottleneck in the communication stream between the tool and the Pro IDE's output pane. ## To Reproduce 1. Select **File > Preferences** from the Arduino IDE menus. 1. Check the box next to "**Show verbose output during: upload**" 1. Click the <kbd>OK</kbd> button. 1. Upload a sketch to an AVR board, megaAVR board (upload tool is AVRDUDE), or the "Programming Port" of a Zero (upload tool is OpenOCD). For some reason, I don't have the problem when uploading to a board that uses bossac as the upload tool (e.g., the "Native Serial" port of the Zero). 🐛 The output from the upload tool slowly streams in to the output pane for seconds after the actual upload has finished. ## Expected behavior The upload tool output to be displayed in the output pane at approximately the same speed as when using it from the command line. ## Desktop ### Original report - OS: Windows 10 - Version: 0.1.4-snapshot.3042c1a Date: 2021-02-08T10:04:20.854Z CLI Version: 0.15.1 alpha [c7403ed2] ### Last verified with - OS: Windows 10, Ubuntu 20.04 - Version: 2.0.0-rc7 ## Additional context I don't have any problems with the rate of the compilation output. ### Related - https://github.com/arduino/arduino-ide/issues/714#issuecomment-1024916301

What I find is that the actual upload finishes just as quickly as you would expect and the sketch is already running, meanwhile the output is slowly trickling in to the console for some time to come.
