Server slowdown

I was wondering does H5P slow down the server ? Will it make alot of requests?

I want to know if I can scale with H5P or should i try a different plugin.

Will my server be able to handle 2000 multiple questions created with H5P?

What about concurrent users on the website? Any limits?

What type of numbers are you guys seeing? Is this better than Learndash? I know you cant scale too well with Learndash.

Thanks. Any help is appreciated.
