Hi cwangv,
I agree with you but our Mango-PC on side is only a data collector and gateway via Persistent TCP Publisher to the cloudserver. The Mango-PC has no webpages to serve for end-users. This is the job for the cloud-server.
Our 268 data sources are 50% BACnet and 40% SNMP and 10% Modbus TCP/IP.
All BACnet-Devices are BACnet Building Controllers (TCP/IP), propper setup with COV etc, minimum network traffic.
The installation is running since 9 years with an other software as data collector and gateway, and now with Mango.
If I want to serve the webpages on side, then I have to install a much larger system as server and data-collector, I know.
MattFox has 127 users to serve, a complete other situation. A web server process with this size needs a lot of RAM and core-power.
The new experience with Mango was there are a lot of adjustment screws and you can watch and tune the system very fine, and you have to do it :)
