Manta Pacific node synchronization is very, very slow

[zhy827827]

I deploy nodes based on this document
https://docs.manta.network/docs/manta-pacific/Manta%20Pacific%20Node/How%20to%20run%20Replica%20Node

The node deployment is completed, but it has been synchronized for a month and still cannot catch up with the latest block height。（So far, there is still a difference of 30,000 blocks）
number=2,438,150 hash=eff862..ceccfd root=7fc8d7..60032e elapsed="87.631µs" age=3d35m43s

Does anyone know what problem caused the synchronization to be very slow?（I don't know how to seek technical support from the official）
