KB01685 - Factors that contribute to latency


  • BlackBerry® Enterprise Server


Latency is the time between the initiation of the transfer in a sending process such as when an email message is sent from a BlackBerry smartphone, and the arrival of the first byte in the receiving process.
The following factors are possible reasons for latency:
  • The time it takes the BlackBerry Enterprise Server to poll for, discover, and queue a new email message.
  • The bandwidth available between the BlackBerry Enterprise Server and the wireless network.
  • The current traffic volume in the wireless network.
  • The BlackBerry smartphone network coverage.
  • The mail servers' responsiveness when accessed by the BlackBerry Enterprise Server, both in server response time and network connectivity between the two servers.
