This guide may help you choose correct hosting and plan for scale.Please remember that this is a simplified approximation for the default UNA setup with standard modules only. The real site can have many more modules from 3rd-party developers (which can affect on-site load, space requirements, etc.) or can be focused on resource-intensive tasks that may call for a different estimation (i.e. video conversions, high-storage sites like pro-level photo sharing, etc.)How to calculate load and choose proper hardware.The load is very dependant on the number, purpose, functionality and quality of installed modules and the site template. Therefore it is almost impossible to predict it beforehand. But if you have a sample setup of the desired site configuration or pre-production setup on the web server, it is possible to at least predict the memory usage. To do it install "Profiler" module, this module shows different timings at the bottom of every page for site administrator (by default). Try to open different pages and watch for memory usage and page execution time.Try open different pages and measure average "Memory" and "Time" values. Let's assume that it is 20Mb for memory usage and 0.5 seconds execution time. Then, if you have a web server with 4G RAM (for example) the web server is capable to handle:4G - 1G (for system usage) / 20 Mb ~ 150 simultaneous requests.Please note, that simultaneous requests aren't a number of online users. Users make requests to the server one time in several seconds or a dozen of seconds.Static SiteIf it is a mostly static site (without much dynamically changing content like the Messenger, Shoutbox, Rocket.Chat, etc) then one request in 30 seconds from one user is likely. In this case, the server is capable of handling the following number of online users:30 (average seconds per one ... Read more
