Connectivity & theoretical infrastructure required

Disclamer

This page is under construction

OpenIMIS (online version) has an client (the computer) and a server (where openIMIS and its database are installed)

Hardware

For the server the minimal configuration can be found here : http://docs.openimis.org/en/latest/install_manual/minimum_requirements.html

For the client, a modern internet browser is required, there is no hard drive requirement, for the RAM and CPU,  it depend of the operating system and other parameters.


Connectivity

openIMIS is a modern application using jquery library, this means the initial load for the application can take time on slow internet connection because those library need to be downloaded once

Measured opening time with Google Chome throttling option

Connection

Download/upload/latency

First loadnext load
(caching on)
High speed connection (>100M/100M/3ms)~2 seconds~1 second
V-SAT 1M/512k/500ms9-15 seconds2-5 seconds
3G 500k/200k/500ms20-28 seconds4-6 seconds
xDSL 128k/32k/150ms50-60 seconds2-7 seconds
2G without EDGE 40k/20k/1000ms3 min~20 seconds
56k/V92 20k/10k/30ms~5 min~40 seconds


Therefore the"minimal" connection required for openIMIS is 2G-EDGE or a 128kbps connectivity
