Incorrect upload speeds with podman push

Issue Description

I am seeing incorrect upload speeds when pushing large container images up from my home office internet connection. I have 1000 Mbps down and 40 Mbps up and Podman reports that I am pushing up at 898.4 MiB/s which is clearly not the case.

Copying blob e3907d99f167 [==========>---------------------------] 1.9GiB / 6.9GiB | 898.4 MiB/s
Copying blob 53426296ad68 done   |

Copying blob cb66ed916443 done   | 
Copying blob f61481d110a8 done   |

Steps to reproduce the issue

Create a very large container image. Mine are around 7GiB in size.
Push up from connection that doesn't have a very fast upload.
Observe incorrect upload speeds.
