Op-Geth syncs extremly slow

[drbenshiller]

I am trying to sync an openbnb mainnet node. However the logs of op-geth seem to indicate that it is importing blocks very slowly. After 12 hours it is still at block 97000. Peercount seems to fluctuate between 0 and 1. At this rate it will never finish.

I had to use non-custom ports, however those are open according to the firewall rules. Is there any way to speed up syncing, by e.g. increasing peer counts or using a public snapshot ?

The .env file is

There is a public snapshot available that can speed up the process. You can find it at https://github.com/bnb-chain/opbnb-snapshot.

Another option is to enable engine sync. You can find instructions on how to do this at https://docs.bnbchain.org/opbnb-docs/docs/build-on-opbnb/geth-sync.

Before the introduction of the engine sync feature, the sync process was expected to be slow because it scanned all the historical L1 data from the L2 start. Using a public L1 endpoint made it even slower. To improve the speed, you can try the following:

1. Use a faster and more stable 3rd party service like meganode.
2. Enable the bsc_fullnode feature. More details can be found in this PR.
