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

Hardware

For the server the minimal configuration can be found here : MO1. Procure a Server

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

Connection

Download/upload/latency

First load

High speed connection (>100M/100M/3ms)

~2 seconds

~1 second

V-SAT 1M/512k/500ms

9-15 seconds

2-5 seconds

3G 500k/200k/500ms

20-28 seconds

4-6 seconds

xDSL 128k/32k/150ms

50-60 seconds

2-7 seconds

2G without EDGE 40k/20k/1000ms

3 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
