Abstract: Particular embodiments described herein provide for an electronic device that can be configured to group two or more small packets that are to be communicated to a common destination, where the two or more packets are grouped together in a queue dedicated to temporarily store small packets that are to be communicated to the common destination, coalesce the small packets into a coalesced packet, where the coalesced packet is a network packet, and communicate the coalesced packet to the common destination. In an example, the size of a small packet is a packet that is smaller than the network packet. In another example, the size of a small packet is less than half the size of the network packet.
