Size of object code
Linphone-sdk has build options to disable features, allowing to reduce the size of generated object code.
For instance, the on Android, armv7 architecture, the size of object code can be less than 10 Mb:

CPU and memory usage
The following table provides CPU and memory usage numbers for some usual scenarios:
| Scenario | CPU % | Resident Size |
|---|---|---|
Audio call with Opus codec, 48Khz, echo cancellation (webrtcaecm at 16khz) Cortex A7 900Mhz (like Raspberry Pi2, with cpu throttling disabled) | 24% (uses a single core) | 20 000 Kb |
Audio+Video call with G711, echo cancellation and VP8 video (VGA @ 15fps), Cortex A7 900Mhz (like Raspberry Pi2) | 80% (uses 4 cores) | 36 0000 Kb |
Audio call with G729, no echo cancelation Cortex A7 900Mhz (like Raspberry Pi2,cpu throttling disabled) | 7% (uses a single core) | 17 000Kb |
3 way conference call with G729, no echo cancelation Cortex A7 900Mhz (like Raspberry Pi2,cpu throttling disabled) | 14% (uses a single core) | 19 000Kb |
Audio call with OPUS, 48Khz, no echo cancelation Cortex A7 900Mhz (like Raspberry Pi2, cpu throttling disabled) | 24% (uses a single core) | 20 000Kb |
3 way conference call with OPUS, 48Khz, no echo cancelation Cortex A7 900Mhz (like Raspberry Pi2 cpu throttling disabled) | 42% (uses a single core) | 20 000kb |
Audio call with G711, no echo cancelation Cortex A7 900Mhz (like Raspberry Pi2, cpu throttling disabled) | 3% (uses a single core) | 17 000kb |
3 way conference call with G711, no echo cancelation Cortex A7 900Mhz (like Raspberry Pi2, cpu throttling disabled) | 7% (uses a single core) | 18 000kb |
