Sync only about 340000 blocks spent more than 15 days

[xuzhitong]

16GB RAM CPU:Intel(R) Core(TM) i5-7500 CPU @ 3.40GHz HDD: Timing buffered disk reads: 94 MB in 3.13 seconds = 30.06 MB/sec I have changed the code only left write blocks and coins collection,and delete all indexes except "mintTxid_1_mintIndex_1" from coins. I saw someone finished the sync only spent less than 1 week. Why does my sync so slowly?

it relies very much on the performance of mongodb, which needs sort of fine-tuning on config.conf, and an ssd array or something like that. I've increased cache file size to 100g in memory, but it seems not to be helpful.

Expecting feature bulk write transactions, instead of creating them one by one.
