You are in: IBM i Technology Updates > General IBM i Operating System > Potential throughput improvement for TCP traffic
IBM i networking infrastructure code has been adjusted to increase the amount of concurrency for TCP configurations. High-performance network traffic can potentially achieve better throughput and reduced latency. Configurations with high bandwidth adapters tend to have the greatest likelihood of seeing an improvement.
Existing TCP configurations will automatically benefit, without requiring any configuration changes.
Required code levels
– IBM i 7.6 <-- PTF number coming soon
– IBM i 7.5 <-- PTF number coming soon
