try some maxthreads configurations and stress situations to see if the server will could handle
500 users. If necessary I can increase the server memory and processing, we have robust cluster.
Actually the server has 4 cores and 8gb of memory.

First, this video is a static file right? If so, just put an nginx or 
such in front of you'r Tomcat, you dont need an application server for 
that, it's just like using a tank to shoot a mosquito :P

off the responsibility of tomcat to deliver the video and I can sleep in peace. hahha

Well, this clever, bandwidth for free.

Is there a place where you can upload your file that will be more scalable and/or faster?
Something like Amazon S3 maybe?
