I would raise the cores count (two cores) and make sure memcached is installed and configured.
To install memcached (on te Koha server): $ sudo apt install memcached To configure memcached to be used by Koha, make sure the relevant koha-conf.xml file contains something that looks like this: <memcached_servers>127.0.0.1:11211</memcached_servers> <memcached_namespace>koha_koha</memcached_namespace> Tell us how it goes!
