This issue is also due to the need to generate citations for each item
in a browse view which can be slow, as each one can require a number of
SQL queries. The citation caching code I describe in the
Hyperauthoship thread would like improve this significantly and was one
of the main reason I was writing it.
I have not had a chance to look at this again since I received Chris'
feedback. When I do I will hopefully be able to provided an updated
version for people to try. Unfortunately, this is still a long way
upstream and requires changes to the core codebase, so is not something
that will solve your problem in the short term.
