Thanks for the feedback and help, Tres. 

Let’s say I want to display an accordion with all events of a month displaying 
quite a lot of data about the event (30-50 events on one page, collapsible 
jQuery accordion). At the moment I get the results and put the objects into the 
result set via unrestrictedTraverse using getPath(). Would it be better to only 
get the path and get the object in the template? Does this make any difference 
performance wise?

Which data of the event objects would I keep as ZCatalog meta columns and which 
not? Documentation is not really helpful on this.

The tricky part is that events are linked with different locations (event 
location, selling points) that are not children of the event object but objects 
in a different folder. The event object itself only keeps the links to these 
location objects and I get them when iterating over the result set in the 
template.

Any advice what would be the best way for this performance-wise?
Is it okay to get the object itself via traversal? Is there a faster way to get 
the object data?
