Maximum number of concurrent request handle?

I am using the Open Trivia DB and I want to know how many concurrent api request it can handle , or does it have any limitation on maximum request we can make per day and/or per user ? any performance issues with concurrent requests ?

We currently have no rate limit on the use of the API.


so do you throttle any particular server or ip for the api calls, because we are seeing for shorter duration no response received from opentdb.
Looking forward to hearing from you on this.
