fast sync takes more than three weeks.

[CNLHC]

I am trying to set up a full node by following the instructions in the BSC-Doc. Without any extra configuration, i believe that i am using the "fast sync" mode.

I totally understand that downloading the state is a slow process. But i think it is abnormal for this process to take more than 3 weeks.

My machine has 32GiB RAM and 8 cores, equipped with 1TiB SSD driver , which meets the suggested requirements in the BSC website.

Currently the knownStates field from eth.syncing is 1605196693, and it is increasing by about 4000-10000 every seconds.

  currentBlock: 9253432,
  highestBlock: 9253496,
  knownStates: 1605196693,
  pulledStates: 1605191168,
  startingBlock: 9227812
}

Do you have any suggestions?

if it takes more than 48 hours, get faster hardware

Do you have any suggestions?

is your SSD directly attached to the node hardware (e.g. not AWS EBS, etc), and is it being shared by other people or otherwise bottlenecked

are you using a suitable fs (zfs with large recordsize will probably wreck your sync performance)
