Insufficient disk performance

Question

Hi,

I am trying to run a full node on Binance Smart Chain. Due to this, the disk performance requirements are high.

I am using a Standard F48s_v2 (48 vCPUs and 96 GiB of memory) with an attached ultra disk LRS (4072 GiB size, 160k IOPS and 4000 MB/s max throughput). Location is France Central.

This seems to be insufficient, the node fails to sync up in time (The blocks are moving faster than my node can process). The maximum observed usage is:

Disk write speed: ~120 MB/s and read speed 5 MB/s.
CPU: 10%
Memory: 26 GB
Ethernet throughput: ~1MB/s

What is the recommended VM specifications to use for such a use case? I couldn't find any offering on Azure with better performance. Is AWS my only option at this point?

Thanks

Answer 1

You can consider to use Hc-series Azure VM.

Instance Name : HC44rs

Core(s) : 44

RAM : 352 GiB

@Orestis Pavlidis

In the metrics you have listed I am not seeing disk performance as a bottleneck. I am not familiar with Binance smart chain, but since it is transactional in nature perhaps you would be better off by using directly attached storage. Something like the Lsv2-series with NVMe storage drives might be a better fit. You will want to go through the Optimize performance page which will make sure your VM reaches its full potential.

Hope this helps. If you are still seeing performance issues, please let us know and we can work with you directly to review your VM metrics.
