quickly copy feature class with attachment

[yockee]

I am in the middle of copying a feature class with large attachment (91K records attachment). The process take 2 hours for copying around 19K of attachment records.

How to speed up the process ? Mathematically, the whole copying will take approx another 8 hours .

versions of software? size of featureclass?  connection related (eg not locally stored)

beyond those obvious ones, this can be consulted for other possibilities

Iam using Postgres 13, Arcgis Enterprise 11.0, Arcgis Pro 3.0. The size of the table is 15Gb (attachment). the feature table itself is really small compared to the attachment (only 91K records).
Update: finally the whole copying finish in nearly 6 hours.
