A question about sync block

[KEY-L-LC]

I am a developer on BSC， I build a node by myself, the version is v1.1.7,but the node has something wrong. sometimes,about 30s to 2m, the node does not sync block, then it will sync about 20 to 30 blocks. time after time, please tell me how to resolve that, thanks very much

Hi, can you please provide some logs?

somtimes it syncs block one by one, 2022-01-26T08:54:31 it synced 23 blocks

Hi @KEY-L-LC I saw the mgas is a bit low.
I thought maybe you could try:

1. prune data
2. enable diffsync

Here are some tips to help you maintain your node

2. Tips for running a BSC full node #502

@j75689 ok,thanks very much. I will try the second acvice, then I will reply for you
