I currently use ARM-KVM with gem5, so reaching the point for checkpointing takes just a couple of minutes and is not a problem.
Just writing a checkpoint takes 10 mins even on locally-mounted SSDs. Before digging into the issue, I just wanted to know if this is normal. Maybe I have to check my system configuration again. Thank you for your advice.
