+This first queue is between the Network card and processing unit. Whenever the I/O threads are too slow to consume all packets from the built-in or extension ports, the '''hardware miss''' counter of the interface statistics will increase over time.
+The load of the I/O threads can be checked at the '''Info''' → '''System Info''' → '''Load'''.
+If this counter increases regularly, you can try the following settings:
+* use sink mode instead of bridge mode, see below [[#Sink Mode]]
+* increase the number of I/O threads: [[#More I/O Threads]]
 === Analyzer Queue ===
+The Allegro has a packet queue between I/O threads and the analyzer threads. This queue

+Please note that the increasing counters at the initial startup of the Allegro can be normal under high load scenarios for a few seconds.
