What is required to achieve gigabit network throughput on EC2? You already selected cluster-compute, 10GB instances with enhanced networking, and your workload is already network-bound, but you do not see 10 gigabit speeds.

A placement group is a logical grouping of instances within a single Availability Zone.
Placement groups are recommended for applications that benefit from low network latency, high network throughput, or both.
To provide the lowest latency and the highest packet-per-second network performance for your placement group, choose an instance type that supports enhanced networking.

http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/placement-groups.htmlTo achieve gigabit network throughput on EC2 instances, several factors need to be considered:
Instance type: EC2 instances with 10 Gbps network performance should be selected. These instances are optimized for network throughput, such as the c5n, m5n, and r5n instance families. These instances also support enhanced networking, which can help improve network performance.
Enhanced networking: Enhanced networking is a feature that uses single root I/O virtualization (SR-IOV) to provide higher bandwidth, lower latency, and lower CPU utilization compared to traditional networking in EC2 instances. To achieve gigabit network throughput, enhanced networking should be enabled on the EC2 instances.
Placement group: A placement group is a logical grouping of instances within a single availability zone that enables low-latency, high-bandwidth network connections between the instances. To achieve gigabit network throughput, EC2 instances should be launched in a placement group. This ensures that the instances are physically close to each other, which can help reduce network latency.
Block storage: To achieve high disk throughput, Provisioned IOPS (PIOPS) can be selected for the instance's EBS volumes. PIOPS can help provide consistent and low-latency I/O performance. Mounting several drives can also help increase the disk throughput.
Biplex networking: Biplex networking can help improve network performance by enabling packets to be non-blocking in both directions, without any switching overhead. However, this feature is not required to achieve gigabit network throughput.
In summary, to achieve gigabit network throughput on EC2 instances, one should select EC2 instances with 10 Gbps network performance, enable enhanced networking, launch instances in a placement group, consider selecting PIOPS for the instance's EBS volumes, and optionally enable biplex networking.
