Network traffic with close intervals from IDE 2.1.1

Operating System
Manjaro Linux
KDE Plasma
Kernel: 6.1.44-1-MANJARO (64-bit)
Graphics Platform: X11

The IDE is from the package manager.

KDE's monitor shows little traffic with seconds in between. What is it the IDE needs to hold hand to?

Hi @ledsyn. Arduino IDE communicates with some of its helper tools via an internal TCP/IP port in your computer on "localhost". Maybe you are seeing that connection. It is immediately between Arduino IDE and the Arduino CLI helper tool via its gRPC interface:
