Unicoi Systems released version 8.6 of their Fusion TCP/IPv4/IPv6 Dual Mode Stack. The TCP transmit performance of Fusion TCP/IPv4/IPv6 8.6 averages 25% higher than previous versions with peaks in excess of 40%, depending on the transmit buffer size. On average, the TCP receive performance is improved by 20% over Fusion TCP/IPv4/IPv6 version 8.5 with peaks at over 30%, depending on the size of the receive buffer size.
To run faster, the Fusion stack has to run smarter, which is why several new features are part of version 8.6. A new socket option is provided for tuning TCP performance by allowing the TCP ACK strategy to adapt to the saturation of the socket receive buffer. Also, a new set of driver API functions allow developers to create a pool of reusable message buffers for receiving packets from the network. Additional changes in the core stack allow drivers to pass packets received from the network to the stack where the actual packet data is contained in a buffer allocated from a different memory space than the Fusion stack’s own heap.
