https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=16166 --- Comment #1 from Jacek Ablewicz <ablewicz@gmail.com> --- Created attachment 49670 --> https://bugs.koha-community.org/bugzilla3/attachment.cgi?id=49670&action=edit Bug 16166: Improve L1 cache performance Bug 16044 introduced two-level caching mechanism to Koha::Cache. By default, get_from_cache() returns a deep copy of the data structures stored in L1 cache (aka "safe mode"). For extremely big and/or complex data structures (like MARC framework hash-of-hashes-of-hashes returned by GetMarcStructure() ), deep-cloning is currently very sub-optimal (i.e., 2-3x slower after Bug 16044); this patch addresses that particular issue. See also: Bug 16044 comments #18 - #23 Test plan: 1) apply patch 2) flush L2 cache if necessary (restart memcached daemon) 3) profile GetMarcStructure() calls before / after patch, e.g. by running some script which calls it often (like catalogue search w/ XSLT processing turned on, etc.) 4) after Bug 16044 + Bug 16166, GetMarcStructure() should be faster than before, in all possible circumstances -- You are receiving this mail because: You are watching all bug changes.
