How to speedup service execution time

Question

When we fetching all levels of cad structure using getStructure API, it took 10 mins to fetch 10,000 documents. How to speed up the service execution time instead of increasing the execution time in backend!!!

I don't have a direct answer as I do not use the getStructure-API, which I think is a service fetching data from a different system like Windchill?

In case the getStructure call is used in some bigger service to find the bottleneck maybe you can add some timing debug logs like

logger.info("Starting");
let strucutre = getStructure();
logger.info("structure received");
// doing something additional with the structure
logger.info("did something with it");

and compare the timestamps from the logs. Maybe the issue is not with getStructure, but with the additional stuff done?

If the issue is with the getStructure-call I guess there is not too much we can do. Maybe the transfer of data from the server its fetching from is so slow? Or the server itself needs a lot of time to find all needed documents? If so, maybe you could cache the structure in TWX and only reload it from server after some time? Not sure of the use case and document update rate.
