Downloading toolchain is very slow

The time required to download toolchain for esp32 is about 1 hour and 40 minutes.
Is it normal?
When I installed a toolchain for ESP8266, it took less than 10 minutes.

I installed HAOS on raspberry PI 3B+ with Samsung bar plus 256 GB USB.
Although the booting medium is the USB drive, it is faster than other USB drives.
According to benchmark using CrystalDiskMark, read/write for RAND4K was around 20MB/s.
So, I believe that the USB drive is not a bottleneck of this problem.

I rebooted HA, but nothing is changed.

Eventually, I got the following message.

I would take a look at your RAM and CPU utilisation while you compile/install.

My guess would be it’s a resource issue.

I did not include sensors for monitoring system, but settings/system/hardware menu shows CPU and RAM utilization.
CPU ram utilizations are 6% and 0.7GB/1GB, respectively.

Is that background level or when you compile?

This is when downing tool chain before compiling.

I’m not sure then. Mine takes minutes for the full compile.

Even 10min for your esp8266 is pretty long I reckon.

Are you on dialup?
