Sync is so slow.

[lambda2003]

Geth version: v1.11.1
OS & Version: Ubuntu

I tried to download all blocks as full sync. It was fast but sync speed was so slow in some point at 9670000. Am I doing wrong?? Any help/comment will help me a lot. Thank you for your support as always. :)

Can you please show

• output of geth version
• what command you're using to run geth
• more logs (maybe as a gist

This will help us help you ;)

@meowsbits Thank you for your help. Mine is stuck in 9679390 block. Any suggestion or advice??

I just updated 1.11.1 version to 1.11.2. But I still have the same issue. Here is my recent log file.

Version: 1.11.2-stable-cbe4a649
https://gist.github.com/lambda2003/44a3c69b0154141640036d4fb31823bd

I can see below in my log file. Is it normal??

[lambda2003]

I just removed all blocks and restarted it. I will keep posting how things are going.

[meowsbits]

Thanks for the updates.

The log you posted has a BAD BLOCK scenario, which means that the remote your node was downloading from fed you a bad block, and your local chain was rolled back enough to sync around it. This is expected behavior for geth.

As for the slow sync, it could be caused by many different things... your internet speed, peers available (which can depend on where in the world your node is located, eg. China?), CPU speeds, etc. Some sections of the chain itself are simply slower to sync than others, too.

If you keep having the problem and can provide as much context as possible with regard to these possibilities, please let us know!

[lambda2003]

Thank you for your comment. :)
FYI. It is slow. Current my block is 9743657 since I start 'geth' three days ago.

currentBlock: 9743657,
highestBlock: 9743725,
knownStates: 484382762,
