  • How to improve http connections performers in TIBCO ActiveMatrix BusinessWorks? using persistent connections

    Manoj Chaurasia

    HTTP persistent connections are the idea of using the same TCP connection to send and receive multiple HTTP requests/responses, as opposed to opening a new one for every single request/response pair. Using persistent connections is very important for improving HTTP performance.

    There are several advantages of using persistent connections, including:

    • Network friendly. Less network traffic due to fewer setting up and tearing down of TCP connections.
    • Reduced latency on subsequent requests. Due to avoidance of the initial TCP handshake
    • Long-lasting connections allow TCP sufficient time to determine the congestion state of the network, thus reacting appropriately.

    Ex. configurations how to use HTTP persistent connections is BW (edit bwengine.tra)

     bw.plugin.http.client.usePersistentConnectionManager=true bw.plugin.http.client.maxTotalConnections=200 bw.plugin.http.client.maxConnectionsPerHost=20 bw.plugin.http.client.ResponseThreadPool=50 bw.plugin.http.client.ResponseThreadPool.type=single/default bw.plugin.http.client.checkForStaleConnections=true
