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 load | next load (caching on) |
|---|---|---|
| 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
