Cross Cloud DB Link performance

Ankur KulDec 6 2022

Hi Community,
Wanted to check if the below is normal in OCI.

  1. A query across two Databases in the "same region" thru DB link runs for about 300 ms
  2. the same query above when run across two Databases in "different regions" using DB link runs for about 2 seconds.
    i.e. is it normal for the cross region database link performance to be almost 6 times worse than within the same region.?
    Thanks!
