EFS slow read on clean Ubuntu 22.04 image

I have Ubuntu 22.04 image, running on EC2 using g4dn.2xlarge instance type. EFS Throughput mode - Bursting or Provisioned (200 MiB/s). And it took ~30 seconds to copy a 300MB file from EFS to EBS. I didn't experience such issues in any other distro (Ubuntu 18.04 or Amazon Linux 2). If I try to copy the file using Amazon Linux 2 - it will take less than 5 seconds to do it. Both servers use the same network flow, same subnet, and VPC. I attached some benchmark tests below.
