[Koha] Help regarding Import batch into the catalog

Dear team, While importing the batch into the catalog in 3.22.4, I noticed it is taking more time for 30000 records. In 3.20 it used to take only less than 30 minutes for both upload marc records and importing batch into the catalog. Is this issue with any of our koha settings? Please guide me if any way of importing data little faster into the catalog. -- Regards T. Suresh Kumar
