AWS EC2 instance specs

I'm trying to get my full node synced with a m5zn.3xlarge, as the documentation describes, but it does not get synced, it oscillates 60-120 blocks from last. Not sure if its due to specs.

Hi @TheSlackOne, we have some tips for running fullnode, maybe you can try these tips

I recommend the i3en.2xlarge.

Thanks for the recommendations, guys, I've also done the snapshot guide steps, and my node is still ~65 blocks away from last. It get to this height relatively fast (several thousands of blocks per hour) and then stucks on this difference. I don't have a clue now.

Log shows:

Finally got synced with the m5zn.3xlarge instance, storage gp3 8000 iops and 250 troughtputs.

I had to use the snapshots.

At some points, it was 64 constantly, until suddenly was 1M blocks away. After restarting the node, got automatically synced.

Took about ~4 days.

I used two nvme disks mounted on i3en.2xlarge, which has better performance than aws ebs, in raid0.
It took a day to complete the sync.
Also use the snapshots.

Aren't nvme physical disks?

I'm not sure if it's a physical disk or not.

However, it is much faster than ebs.
