Cpu throttle

If you're in a cgroup (cgroups (abbreviated from control groups) is a Linux kernel feature that limits, accounts for, and isolates the resource usage (CPU, memory, disk I/O, network, etc.) of a collection of processes.) then you can use the command cat /sys/fs/cgroup/cpu/cpu.stat it will give you a result like:

nr_periods 0
nr_throttled 0
throttled_time 0

If nr_throttled increases every time you run the command it means your process is throttling.

SSH local port forwarding

ssh -L {local_port}:{remote_internal_ip}:{remote_port} {ssh_ip}

venv

Create a new virtual ENV

python -m venv environment1

Use the virtual ENV

source environment1/bin/activate

SCP

Using SCP we can transfer file over TCP so it's a fast approach to consider. We need to have SSH connection permission to use SCP.

Large files

SCP is a fast approach itself but if your file is so huge even SCP can take so long. To resolve the issue you can enable compression, it will be much faster but will also increase CPU usage.
