Backtrace

Hello, I use snapshots to resynchronize node data to save my disk space, but I find that I have not been able to synchronize the latest block height, and the currentBlock value queried using eth.syncing is catching up with the highestBlock every time The value will stop changing, which causes the currentBlock value and highestBlock value to always differ by 50-100 block heights. Unable to end the eth.syncing state, but the log information shows that the block height of the browser has been caught up.Through monitoring, it is found that the host hardware resources have not reached the bottleneck。

1.first of all, let me do some clarification of the 2 concepts:
currentBlock: it is the head block from the local chain, e.g. its header/body are downloaded, verified and inserted.
highestBlock: the highest block number known when syncing started, it could be header downloaded, but its body is still missing.
2.currentBlock fall behind of highestBlock, can not catch up:
it could be similar to the issue: #1198
the state healing takes lots of time, it could be improved by this PR: #1226
3.but the log information shows that the block height of the browser has been caught up
May I know what is the browser here?

ok, then your log only shows the header is imported, but the block has not been imported yet.
