I am back after a small test.
@timconsidine Yes it is a large number of small files.
After checking with different formats. Only started to work as it should with ".tar" format. It works like lightning with a new folder or in the current folder where the application is located.
With this format, the extraction takes in a second and is ready.
And I use a server from Hetzner - CX41 (Intel, 160GB Disk and 16GB RAM).
EDIT:
I would still add that I had resources allocated during the test: 4GB ram and 75% CPU. I still checked with the standard one, i.e. 256MB ram and 50% CPU - with ".tar" format it extracts just as fast.
