Performance degrade when upgrading from 3.5.3 to 4.25.1


We are currently working on upgrading our liquibase version from 3.5.3 to 4.25.1(the latest one). One major concern we are seeing with this is that the time taken for the update has increased by 3 times the previous duration. On 3.5.3, the entire schema creation was taking us 1.5 ~2 hours maximum, but now, it is taking 6~6.5 hours. Any pointers as to why this huge performance impact? Are there any additional features which we can disable to reduce the duration?
