sync with mongo_db_plugin too slow about cryptokylin-testnet

[winlin]

@noprom do you have same issue?
@hippokylejan can you disable the mongo_db_plugin and check the sync speed?

@hippokylejan Which kind of nodeos version do you use?
As far as I know, syncing data to mongodb instance is a computation expensive operation, could you please try to scale up your machine which runs nodeos? Such as 8 Core, 64G.

Any feedback is appreciated.

i use nodeos v1.2.2. it seems that mongodb can use lots of memory. i will try to increase the memory, thanks a lot
