In Koha, the sip2_resource_last_modified key is updated any time the SIP config is edited from the SIP2 editor in the staff interface ( institutions, accounts, system preference overrides ).
If sip2_resource_last_modified is missing from memcached, Koha SIP emits "Couldn't find sip2_resource_last_modified, considering configuration not up to date" in the logs, and fetches the entire configuration from the database, *for each request*.
This causes SIP performance to drop significantly. In my production testing with 83 institutions and 171 accounts the login message response time dropped from 0.283 seconds to 2.899 seconds.
I think the solution is pretty simple. If there is a cache miss on sip2_resource_last_modified, SIP should load the config from database as it does already, but then it should also set sip2_resource_last_modified!
Test Plan:
1) Apply this patch
2) Prove t/db_dependent/Koha/SIP2/SIP2ModuleMigration.t

Net::Server - The SIP server is a Net::Server::Prefork server
XML::LibXML
XML::Parser
XML::Simple - for parsing the config file
UNIVERSAL::require - for loading the correct ILS interface module
Clone - for running the test cases
LOGGING
SIPServer uses Koha::Logger for status and debugging messages.
