32 topics; Easy selected = 5s
32 topics; Easy + Medium = 8s
32 topics; Easy + Medium + Hard = 11s

Event Timeline

selecting easy tasks and selecting all the topics from the list,

We have to do a separate search query for each topic (T242560), so yes this can take a really long time. We should probably rework this soon.
