Running Liquibase code 3.5.3 is slow

Hi,

I have the set of Liquibase scripts which recently got migrated from 2.0.1 to 3.5.3.  Scripts which were running in 25 mins in 2.0.1 is taking about 1 hr 55 mins to execute in 3.5.3.  We cannot afford this increase in time.

Any help is highly appreciated?

Thanks
