Expert Network Performance Analysis

Digital Innovations Global ensure on-premise to cloud migrations run smoothly, by performing in-depth professional expert network performance analysis. We are able to quantify and document infrastructure resource requirements, to eliminate bottlenecks, application issues, and to provide performance improvements for our clients by identifying:

  • Network traffic flow between systems.
  • LANs which are overloaded.
  • Servers traffic which is affecting other systems.
  • Servers which are too overloaded or congested to respond.
  • Network devices which have incorrect configurations.
  • Slow file transfers.
  • Database connectivity problems.
  • Domain logon failures.
  • Slow HTTP Web applications.
