Does PostgreSQL database performance drop in docker container?

Question

PostgreSQL

Will PostgreSQL performance drop if placed in a docker container? than without it.
We have projects in which tables are already 70 million rows each, and it is important that the performance of hardware, namely the ssd nvme disk, does not degrade from virtualization factors, because of this, they abandoned virtual disks in favor of forwarding pci-e directly to the machine in which they will spinning all the databases (as they didn’t dance with a tambourine, they couldn’t overcome the 50% performance degradation of the virtual disk in the KVM virtual machine compared to the real one), if you pack each database in a separate docker container, then it will be more convenient in terms of administration, BUT there is fears of reducing iops and other parameters important for the database.
