Sync slow when started as a storage mining node

[syntrust]

System information

• branch: tm_w3q_sstorage_miner_debug
• testnet: (https://testnet.web3q.io:8545)

Expected behavior

Sync fast till the latest block.

Actual behavior

1. Slow syncing with the following log. Notice that it takes 1 sec to sync 2 blocks.

   INFO [04-23|10:49:07.725] Finalizing commit of block               height=11171 hash=c95194..a7d4bc
   INFO [04-23|10:49:08.839] Finalizing commit of block               height=11172 hash=b2a00d..d6ae92
   INFO [04-23|10:49:10.009] Finalizing commit of block               height=11173 hash=c37745..353a3c
   INFO [04-23|10:49:10.226] Finalizing commit of block               height=11174 hash=96a52b..4cde23
   INFO [04-23|10:49:11.341] Finalizing commit of block               height=11175 hash=5a1217..0890dc
   INFO [04-23|10:49:11.728] Finalizing commit of block               height=11176 hash=7b431f..edcfe8
   ...

2. Sync fast until block 10xxx and continue with the slow syncing when shutdown the node and restart, while the latest block is 12xxx.

Steps to reproduce the behavior

Remove chain data in geth folder and restart the node with the following sstorage params

--sstorage.shard=128k,0 \
--sstorage.file="/root/data/node/ss0.dat" \
--sstorage.mine=true \ 
--sstorage.minercontract="0x0000000000000000000000000000000003330001" \ 
--sstorage.txsigner=0x2cff0b8e36522eba76f6f5c328d58581243882e4 \

The sync slow is because this node is set as a validator, so after syncing to the latest block, it needs to verify and commit the block again. so it will be slow. To make it sync fast, you can run the node without --mine, after sync to the latest node, stop it and restart with --mine.

Verified that it syncs fast without --mine:

And after fully synced, restart with --mine worked as expected.
