How to sent more than 4 Soap parallel request via MID server without a delayIssue You may have a requirement to send more than 4 parallel requests to an end point. But you can notice that only 4 among all requests are hitting the end point. You can use any packet capture tools to make sure your end point is receiving all of them simultaneously. From SOAP Ui also you can mock these request and you may see the delay as shown below CauseThis can be controlled from MID server via a Property glide.http.connection_mgr.max_connections_per_host. Like in normal SOAP call, this can be added to the MID server property list as well Property controls how many of the glide.http.connection_mgr.max_connections can communicate in parallel with any particular host. If the maximum setting for any of these values is reached during normal operations, a script or background thread may have to wait briefly to obtain a connection. This is well defined in the DOCS ResolutionAdd the property glide.http.connection_mgr.max_connections_per_host to a desired value in MID server host machine's CONFIG.XML After modifying the property value to 10, you can see the below logs where all the requests reached the end point at same point in time.
