commit work taking more time in hana system

Hello All,

One of my client move to Hana system from ecc. but in some objects we found performance degradation . As we analyse its happen due to database commits. we are using some finance BAPI and using Bapi transactions commits. In this case data base commits taking 4 times more then non HANA systems .

So please suggest me , what we can do in this. because its become a challenge to our team.
