→Skipped packets at low analyzer load
| Line 68: | Line 68: | ||
The '''Allegro Network Multimeter''' conserves energy in very low traffic situations. Large packet bursts can lead to a high traffic situation so the analyser threads cannot keep up with the incoming packets fast enough during the period of power adjustment. After that small period of time, the analyzer threads are again fast enough to process the traffic. | The '''Allegro Network Multimeter''' conserves energy in very low traffic situations.

If this occurs, the option '''Analyzer queue overcommit''' at '''Settings''' → '''Global settings''' → '''Expert settings''' can be enabled. This option can only be used in '''Sink mode''' and it increases the queue size to be able to buffer network burts during a short time period. The disadvantage is that the queues are overcommitted so it can happen that the network card does not have enough buffers available for incoming packets. | If this occurs, the option '''Analyzer queue overcommit''' at '''Settings''' → '''Global settings''' → '''Expert settings''' can be enabled.
