Limits of a Download Server
for Large Downloads
Probing the maximum number of users without
deterioration of performance
In this test up to 100 users download a 32 MB file from the web server every 30 seconds. The web server is connected to the network with a GigaBit network card.
In the graph we can see that the download times per user are almost constant until about 50 users are active at the same time.
A maximum of 50 users can be active simultaneously until the server's and the network's limits are hit.
