Activities: Realtime Quiz
You may want to consider using the Active quiz activity, instead of this, older, Realtime quiz activity. Active quiz is based on Realtime quiz, but adds question bank and gradebook support, feedback charts, better controls for the teacher, group support and many other useful features not found here.
A multiple-choice quiz designed for use in a face-to-face lesson.
Each student receives each question at the same time with a time limit to answer it (default 30 seconds). In between each question the correct answer is displayed, along with the number of students giving each answer (and some statistics about the percentage class / individual correct answers). This allows each question to be discussed before moving on.
Teachers can review the answers, once the quiz is finished, to identify any areas that need to be covered again.
Recent improvements (2010) include:
- Ability to add a picture to each question
- More attractive question display
- Easier question editing
- Reduced network traffic & improved stability (particularly on wireless networks)

what would be the ideal value for the AJAX waiting time with 100 or 200 simultaneous students answering the questionnaire?
All I can say, is that the plugin is working fine for me, so there must be something different about your setup that is causing a problem.
In addition, I would like to give the student the opportunity to take the quiz at any time, without the teacher's need to follow the test in real time.
With the plugin you are making available, would it be possible to use it as I described above?
This plugin is designed for live classroom usage to gather responses from a class, with the quiz under the control of a teacher. There is no option for students to start a session without the teacher being present, nor is there an option for different students to start at different times (when the quiz is running, everyone sees the same question at the same time, with the time limit countdown also occurring at the same time).
What you are asking for might be possible with a custom question behaviour ( https://moodle.org/plugins/?q=type:qbehaviour) or, more likely, it would require a custom activity type (something like that may already exist, I don't know of any such activity off the top of my head, or you could contact my employers, Synergy Learning, and we could discuss how much it cost to develop something like for you).
