[Koha-devel] Memcached and Koha

Hello all, I'm trying to speed up Koha 3.8 by enabling memcached, following the instructions in the wiki (http://wiki.koha-community.org/wiki/Performance). But I found that OPAC search performance is almost unchanged with memcached enabled. By looking at memcached stats and MySQL query log, it seems like memcached is only used to store Koha's config (koha-conf.xml). The query to MySQL is exactly the same with or with out memcached. I suppose that once memcached is enabled, all preferences should be read from memcached instead? Is there anything else I should do to get memcached fully working with Koha? FYI, I'm running Koha 3.8.5 on Ubuntu 12.04 using koha-common package. Thank you, Pongtawat
