Long-term recovery via barman-cloud-restore

[Kacblm]

Hello everyone!
I use GKE, cnpg and GCS to store backups in a bucket. When I run the command barman-cloud-restore --cloud-provider google-cloud-storage gs://my_bucket/ db-test-cluster 20251031T010011 ./restore, the command downloads the archive (about 100 gb) and unpacks it, there are .tar.snappy files. It takes a very long time, I'm looking at the speed of about 40-50 Mbps. If I run gsutil -m cp gs://my_bucket/base/20251031T010011/*.snappy from the same pod, the download proceeds at a speed of 350-400 Mbps, the CPU at this moment uses all the resources that are allocated to it, but when the barman-cloud-restore script is running, the CPU always 0.8 does not rise more.
Help please...
