Yes, it is cached on oacs-5-1. However, the problem is that it still takes a long time on the first page hit.
I think (but haven't tested it to verify) that a small increase in speed to site_node::get_children could be achieved by changing
site_node::get_from_url (and also get_url) and use something like this:
if { ![catch { nsv_get site_nodes $url } result] } {
return $result
}
instead of this:
if {[nsv_exists site_nodes $url]} {
return [nsv_get site_nodes $url]
}
It might help since I suppose nsv_exists would take almost as long to execute as nsv_get ... but that is only my assumption.
