PCoIP Connection Manager and PCoIP Security Gateway Performance Limits

The following statistics represent the performance limits of the PCoIP Connection Manager and PCoIP Security Gateway with a minimum system configuration. You can exceed these limits, unless indicated, with more powerful systems.

PCoIP Connection Manager Limits

Session Establishment Limits

Based on the minimum connection manager system requirements, the PCoIP Connection Manager can establish the following number of sessions:

  • 40 simultaneous in-process session establishment sequences

  • Up to 400 simultaneous client communications

PCoIP Security Gateway Limits

Session Limits

Each PCoIP Security Gateway supports a maximum of 5,000 simultaneous sessions. You can lower this limit by changing the MaxConnections setting in /opt/teradici/pcoipcm_data/data/SecurityGateway.conf. If you need to support more than 5,000 simultaneous sessions, deploy additional PCoIP Connection Manager and PCoIP Security Gateways behind a load balancer.

Bandwidth Limits

When using the PCoIP Connection Manager and Security Gateway there are certain session establishment and session bandwidth limits when dealing with external connections.

The following table outlines the RAM, vCPU and correlated estimated bandwidth support for all combined concurrent sessions:

vCPUs RAM Estimated Bandwidth
2vCPU 7.5 GB RAM ~ 365 Mbit/s
4vCPU 15 GB RAM ~ 830 Mbit/s
8vCPU 30 GB RAM ~ 1100 Mbit/s

Estimated Bandwidth

These are estimated bandwidth levels. The bandwidth can vary based on the host, OS, CSP, etc.

1100 Mbit/s is approximately the maximum bandwidth that can be achieved. Additional gains may be possible with larger sizing.
