It should be noted that once you have a class larger than 100 users the quality of the presentation will be compromised. The BBB vendor recommends hosting sessions of 100 users (or less). This is not hard-coded, you can have 101, 102, etc. However, as more users join in the session, in general overall performance may be compromised, due to the extra server load and data usage.It should be noted that these capacity recommendations have been advised by the vendor/developers of BBB. iKamva is a seperate platform to BBB.|
