What is Memcached?
"Free & open source, high-performance, distributed memory object caching system, generic in nature, but intended for use in speeding up dynamic web applications by alleviating database load" (https://memcached.org/).
Why we should use Memcached with Koha?
Memcached can boost the performance of Koha.
I have tried to enable Memcached with Koha versions 17.05.x to 18.05.x.
Check Memcached working with Koha
Open Koha > About Koha > Server Information

| The red flag indicates that Memcached not working |
Install Memcached
sudo apt-get install memcached
Configure Memcached with Koha
Open Koha configuration file and make changes for Memcached.
sudo mousepad /etc/koha/sites/library/koha-conf.xml
Find the lines mention Memcached. Line numbers around, 308, 309.
Enable line numbers by checking Options > Line Numbers from the menu.

| Memcached settings in koha-conf.xml file. |
127.0.0.1:11211
The line should look like this;
<memcached_servers>127.0.0.1:11211</memcached_servers>
Add the following namespace,
koha_library
The line should look like this;
<memcached_namespace>koha_library</memcached_namespace>
 |
| Memcached configuration |
Save and close the file.
Restart Memcached
sudo service memcached restart
Now check the Koha > About Koha > Server Information page,
