I hope this is in the right place, if not, feel free to move.

We provide software that provides a soap call to the Eportal api to update the students roll call. At the moment we have 25-35 students with no issues, but each time we extend this to say 80+ the facility data server keeps refusing the call and eportal becomes unavailable. Just wondering if anyone else here has a similar setup with these issue, and if so, what sorted it?

Thanks in advance,
