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?
