Ansynchronous when using "Call transaction"

Hi All,

I have a question when call transaction, after the transaction called, the result is not updated timely , but have to wait for a few seconds some times, it seems that it is not synchronous , I read the documentation about the call transaction , it is as follows:

Is the "S" mode can solve the problem?Why it can solve the problem ? And what is the "L" mode mean?

Thank you very much.

Regards,

Chris
