Our projects are generally configured to poll every 5 minutes for changes. A number of these projects use the main branch for development within the same vob. We now can get into the situation where the polling (or generating a change set) can take a really long time if the project to be polled has not had any changes in a while but other projects using the same branch (typically main) have made a lot of changes.

Could the polling be changed to only look for changes since the last poll, not the last build? Otherwise the change history that comes back includes potentially 1000's of changes from other projects. Any other solution that addresses this would be great!
