Recently, I've been working on a Business Process that processes a large JSON FHIR message containing up to 50k requests in an array within the JSON.
Currently, the code imports the JSON as a dynamic object from the original message stream, obtains an iterator from it, and processes each request one at a time in a loop.
We are experimenting with IIS, as the PWS will be gone in newer versions.
The code which is executed, takes 15ms to run. If we execute it through PWS (REST), there is some overhead and the total execution time is 40ms, which is acceptable. However, if we go through IIS, it takes 150ms or sometimes even more.
Both PWS and IIS are running on the same server as IRIS in this case. No optimisations have been done on IIS.
Any suggestions on where to look/what to optimize on IIS?
