Hi all, I have 2 Koha instances 16.11, both ubuntu 16.04 and apache 2.4.18. One of them has memcached and plack active, they both seem to have equal performance. These 2 instances have mysql 5.6.26 and the same database for testing purposes. Is there a way to find out if plack is working 100%? Can't really find differences in performance.
