Need inputs for throughput sizing for Load balancer and firewall for API Gateway

  • 1.  Need inputs for throughput sizing for Load balancer and firewall for API Gateway

    Posted Dec 18, 2015 03:25 AM

    We have a multi-site setup requirement and we are sizing load-balancers and firewalls on remote sites. We are looking for maximum payload size that can stream through these devices in any-given time. What is the maximum payload size that can be received by the gateway (request) from the internet and what will be the max value in the response ?

     

    I have referred to the below two discussions. But I am confused if its 50KB or 2 MB after going through the details.

    Optimize for mixed workload APIs (Large and Small payloads)

    How does one manage/limit the size of streaming attachments in CA API Gateway?

     

    Kindly provide help.

    Hi,

     

    You can check the cluster wide property  io.xmlPartMaxBytes on the gateway. The default is around 2.6 MB

    We also do a control on the request and response payload by blocking request/response greater than a set value per policy by comparing per policy value with request.mainpart.size and response.mainpart.size

     

    I found this KB file on support site.
