Hello all, I am working on an video-conferencing application using Angular and Nodejs, I came to know about webRTC then openvidu. While exploring I read [this medium article about load test results.](https://openvidu.medium.com/openvidu-load-testing-a-systematic-study-of-openvidu-platform-performance-b1aa3c475ba9). I will attach the image of table also here. I have doubt in that table.  
What does session mean here? Like say for example in first case (c5.large) case what is session and also who are subscribers?  
Thanks for reading it till here. It would be great if someone just explain this table.  
Thanks and Regards  
Tanweer Ali.

A Session is a videoconference room where users can connect to publish and receive video.

So when it is written that 4 sessions are possible that means 4 sessions at one time or 4 sessions one by one?

Why would there be a limit of sessions established one by one? If you read the article you will better understand the test results. The load test is measuring the amount of media streams that can be sustained at once, depending on the instance type. And the amount of media streams depends on the amount of users sending and receiving media, which finally depends on the amount of sessions established at once.

Cheers
