+### FIFO
+
+**FIFO**: concurrent-safe auto expandable queue.
+
+#### pros
+Client is able to enqueue as many items as needed.
+
+#### cons
+It is slightly slower than FixedFIFO.
+
+### FixedFIFO
+
+**FixedFIFO**: concurrent-safe fixed capacity queue.
+
+#### pros
+FixedFIFO is, at least, 2x faster than [FIFO](#fifo).
+
+#### cons
+It has a fixed capacity meaning that no more items than this capacity could coexist at the same time.
