I have downloaded and installed the latest .LRN 1.0 beta 1, and am using OpenACS 4.6.2 beta 1, and postgres 7.2.1. When I create a class, and then click on Class Home, things run very slowly.
It seems that this is down to a reasonably complex select statement (see end of this message), which on my (debian) machine, when I run under psql, takes a little under 30s to complete. My machine is by no means slow - so if nobody else is seeing this problem, perhaps it is something to do with my installation...
The select statement is:
select file_storage__get_package_id(fs_objects.object_id) as package_id,
(CASE WHEN fs_objects.type = 'url' THEN (select site_node__url(site_nodes.node_id)
from site_nodes where site_nodes.object_id = file_storage__get_package_id(fs_objects.parent_id))
ELSE (select site_node__url(site_nodes.node_id)
from site_nodes where site_nodes.object_id = file_storage__get_package_id(fs_objects.object_id))
END) as url, fs_objects.object_id, fs_objects.file_upload_name, fs_objects.name, fs_objects.live_revision, fs_objects.type,
fs_objects.content_size from fs_objects
where fs_objects.parnt_id in (2368)
and 't' = acs_permission__permission_p(fs_objects.object_id, '290', 'read')
order by fs_objects.parent_id, fs_objects.sort_key, fs_objects.name;
