The appropriate method to choose text using QTextCursor without affecting performance is to use the QTextCursor::movePosition() method with the MoveMode parameter set to KeepAnchor. This method moves the cursor to the desired position while keeping the current selection (if any) intact, rather than clearing the selection and creating a new one. Additionally, you can also limit the amount of text being selected by specifying the number of characters to select using QTextCursor::setPosition() or QTextCursor::setPosition(), and then calling the movePosition() method. This way, you can select only the required text, minimizing the impact on performance.
