Hi Rubén,
you can reduce the load created by the community list generator (that is
also used on the repository home page, by the way) by enabling caching.
See here in dspace.cfg:
https://github.com/DSpace/DSpace/blob/master/dspace/config/dspace.cfg#L1943
Note the comment for this option (Manakin = XMLUI):
# Normally, Manakin will fully verify any cache pages before using a
cache copy.
# This means that when the community-list page is viewed the database
is queried
# for each community/collection to see if their metadata has been
modified. This
# can be expensive for repositories with a large community tree. To
help solve
# this problem you can set the cache to be assumed valued for a
specific set of time.
# The downside of this is that new or editing communities/collections
may not show up
# the website for a period of time.
If your repo admins are DSpace super-admins, you could instruct them to
clear the cocoon cache [2] whenever they create/rename a
collection/community, to have the change show on the community list. You
might also like to give your repo staff a heads-up that the community
sizes (if shown) will be cached too, so they shouldn't think of these
numbers as 100% accurate.
Thanks a lot for mentioning this issue by the way, I too had noticed
problems with the database connections. However, until your e-mail made
me look at the community browser code [1], I didn't know/remember that
the caching option exists. Note, I haven't tried it out myself yet, but
I'm going to very shortly!
