How to speed up database synchronization?

Question

After stellar-core synchronization DB filling began. At a rate of approximately 1.5% per day (

It can affect database synchronization speed? Can it be possible to use a snapshot of the base?

If all you want is to sync to the current state of the network you should not specify CATCHUP_COMPLETE=true and instead set that to false. The configuration that you used is to setup full nodes that verify the entire history from genesis (useful when setting up Horizon nodes that understand all of history).
