I helped Nima get acs-developer-support fixed (it had to do with the bad repository files I just fixed) and did some browsing around with supplied accounts.
I am logged in via ext-auth as mazloumi, with developer support on. The front page comes up in 3 seconds (lots of 200msec permission check), not 20, but it may be cached.
While going to site-wide administration to flush the cache, I found that that page took 18 seconds, almost all here:
18061 ms
dbqd.acs-admin.lib.service-parameters.services_select: select nsdb0
select package_id,
ap.package_key,
acs_object__name(package_id) as
instance_name,
apm_package_type__num_parameters(ap.package_key)
as parameter_count
from apm_packages ap,
apm_package_types
where ap.package_key =
apm_package_types.package_key
and package_type = 'apm_service'
and (
acs_permission__permission_p(package_id,
'872797', 'read') = 't'
or acs_permission__permission_p(package_id,
acs__magic_object_id('the_public'), 'read')
= 't'
)
and (ap.package_key != 'acs-subsite' or (select
parent_id from site_nodes where object_id =
package_id) is null)
order by instance_name
After flushing the cache, I can still access the front page in 4 seconds. Not great, but not awful.
I did some more random browsing. Most pages take 2-3 seconds, and the only real reason is a bunch of permission checks like:
170 ms
dbqd.acs-tcl.tcl.acs-permissions-procs.permission::permission_p_not_cached.sele\
ct_permission_p:
0or1row nsdb0
select 1
where 't' = acs_permission__permission_p('616213',
'872797', 'portal_read_portal')
I browsed as both the admin user and a regular .LRN user. I could not repro the 20-second load times.
Issues:
1) Can we fix all of these permission queries so that regular page loads aren't 3 seconds?
2) How can Nima use developer support while logged in as a regular user, in order to try and repro the 20-second problem with proper instrumentation available?
