WorldServer API - too much traffic

hi,

we are trying to communicate with WorldServer using wswebservices.dll, but we have found that it returns much much more data than required.

E.g. to query the list of active projects using WSWorkflowManager.getProjects(...), it takes about 5-10 minutes, and generates about 100MB traffic or more. Then it returns only 34 projects.

The problem is that together with the each project, it also returns the related client object, and with the related client object, it also returns all the users (hundreds) of this client, it also returns the creator user, its vendor etc, so much more things than required. Is there any way to get only the core data?

Thanks in advance, 

Tamas
