[Koha-bugs] [Bug 7886] C4/ShelfBrowser slow SQL performance

http://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=7886 --- Comment #4 from Dobrica Pavlinusic <dpavlin@rot13.org> --- Created attachment 8895 --> http://bugs.koha-community.org/bugzilla3/attachment.cgi?id=8895&action=edit Bug 7886 - C4/ShelfBrowser slow SQL performance ShelfBrowser uses two SQL queries with syntax WHERE ((cn_sort = ? AND itemnumber < ?) OR cn_sort < ?) AND homebranch = ? AND location = ? AND ccode = ? homebranch already has index, and adding indexes on ccode and location improves performance by 30% for each query since MySQL is able to use index_merge intersect(items_ccode,homebranch,items_location) -- You are receiving this mail because: You are watching all bug changes.
