 ==== Low analyzer load and drop ====
-This happens if the Allegro is in a powersafe mode and a large burst of traffic arrives at the Allegro. This leads to minor packet drops . The solution is to use the [[#Sink Mode]] and to activate the '''Analyzer queue overcommit''' at '''Settings''' → '''Global settings''' → '''Expert settings'''. This allows to buffer sudden network bursts.
+This happens if the analyzers of the Allegro are in a powersafe mode and a very high and large burst of one connection arrives at the Allegro. This issue has happened at customer installations with 40G Links, an average saturation less than 5GBit/s and connection bursts above 10GBit/s. This can lead to minor packet drops as the wakeup of the analyzers is not fast enough. The solution is to use the [[#Sink Mode]] and to activate the '''Analyzer queue overcommit''' at '''Settings''' → '''Global settings''' → '''Expert settings'''. This mode allows to buffer network bursts. This mode is not available for the bridge mode.
