Functions Performance

Performance of a function call dramatically depends on "nature" of the function and underlying algorithm. Here are some examples:

  • Synchronize function of a Device context is very fast as it just schedules a synchronization and returns.
  • Execute query function will generally have noticeable performance effect which depends on query complexity and size of its source dataset.
  • Calling a function that matches a device operation takes time required for device I/O but don't cause server-side CPU load.
  • If a remote function was called (e.g. an Iotellect Client has called it from an Iotellect Server or a consumer server has called it from a provider server in a distributed environment), additional time will be required to send a corresponding request to the remote server and get the response. This time is generally equal to network round-trip time reported by ping command.
