Persistent HTTP with Tibco

Tibco BusinessWorks 5.6+ supports persistent HTTP connections. The only thing you must do to enable it is setting in tra file variables:

bw.plugin.http.client.usePersistentConnectionManager=true
bw.plugin.http.client.usePersistentConnectionManagerForSSL=true (5.12+)
bw.plugin.http.client.checkForStaleConnections=false

You may also find useful:

bw.plugin.http.client.maxConnectionsPerHost=[20]

bw.plugin.http.client.maxTotalConnections=[200]

bw.plugin.http.server.acceptCount=[100] # socket accept queue length
bw.plugin.http.client.ResponseThreadPool.type=single

bw.plugin.http.client.ResponseThreadPool=[10] #thread pool size for concurrent req-resp HTTP activities
