How to speed up BAPI_USER_GET_DETAIL calls.

[avhz]

Hi :)

I see that the project is possibly stagnating, however I would be grateful if someone can help me with speeding up BAPI_USER_GET_DETAIL calls.

I need to query many users (to retrieve email addresses), and it takes quite some time.

My code is (roughly) the following. Is there a better way?

def query_user(self, username: str) -> dict:
    data = self.connection.call(
        "BAPI_USER_GET_DETAIL",
        USERNAME=username,
    )
    return data
    
def query_user_email(self, username: str) -> str:
    data = self.query_user(username)["ADDRESS"]["E_MAIL"]
    return data
    
def query_user_emails(self, usernames: list) -> dict:
    emails = {usr: self.query_user_email(usr) for usr in usernames}
    return emails
