Error Observed On Bor: synchronisation is slow

Created by Daniel Anthony, Modified on Thu, 11 Jan at 5:20 PM by Daniel Anthony

Description: If Bor synchronisation is slow it could be due to either of the below reasons:

  • The node is running on a fork - means at certain point the block production was done by forking on a different block and that has impacted the further block production
  • The machine is not working at optimum levels and could be with insufficient resources.

This can be addressed by checking on:


  • IOPS stands for Input/Output state of cycle
  • The rate of reading is usually higher than write speed
  • 6000 is the recommended range for IOPS

Processing Power

  • Processor has to be 8 or 16 core
  • RAM: 32 GB is the minimum; 64 GB is recommended
  • Block import should be more than 2 block for every second
  • Node sync rate should be at 15-20 blocks every 8 secs

Solution: As the issue is more about lack of hardware resources try upgrading it to double of the current specifications.
