Transaction getting delayed at gateway

  • 1.  Transaction getting delayed at gateway

    Posted Sep 08, 2020 03:36 AM
    In our prod environment (Three node gateway cluster), API Gateway is receiving request from tomcat (Java environment) and we saw that at the time of peak traffic gateway start receiving requests after 5 - 10 seconds which ultimately cause a delay in real time transactions for the users. Once API gateway policy start execute transaction got complete in milliseconds as expected.
    So the delay is in between tomcat and gateway.

    Current setting at gateway
    io.httpMaxConcurrency - 750
    io.httpCoreConcurrency - 500

    Our production is highly impacted from last week. Please let us know what to do ASAP.
