Hi
When I run a report using the wizard e.g. for one species, and I 'Restrict the report to one or more sources' and then restrict by 'Survey Tags', then the report takes a very long time - say 4 minutes.
If I don't restrict the source, or just restrict the source to one survey then the report is delivered in just a few seconds.

Can anyone explain why the difference in time and if anything can be done to speed things up.

Many thanks
Kathryn
