Wondering how to increase Memcached memory? We can help you with it.

Here at Bobcares, we have seen several such Memcached related queries as part of our Server Management Services for web hosts and online service providers.

Today we’ll take a look at how to set to a larger memory value for Memcached

Know more about Memcached

Memcached is a high performance distributed memory caching system. And it is mainly used to speed up web applications by reducing the database load.

Memcached does this by storing the data objects in dynamic memory, due to which whenever a request is sent to the database, Memcached renders the contents stored within it. As a result, it speeds up the web application.

How we Increase Memcached memory

Now let’s see how our Support Engineers increase the memory of Memcached.

By default, the memory allocated to Memcached for object storage is only 64MB.

The configuration file of Memcached is in the path /etc/sysconfig/memcached. Here we need to change

# set ram size to 2048 - 2GiB

CACHESIZE="4096"

For some distro the location is different and it is at /etc/init.d/ with the file name Memcached.

Here we need to change the values as shown below,

# set ram size to 8MBytes to 256MBytes

MEMSIZE=256

We can also update the memory value by running a command as follows,

shell> memcached -m 3072

NOTE: Don’t specify a memory size larger than the available RAM. If you specify a too large value, then some RAM allocated for Memcached uses swap space, and not physical RAM. This might finally lead to some delay in storing and retrieving values, because data is swapped to disk, instead of storing the data directly in RAM.

Conclusion

In short, we can set a larger value for Memcached memory by editing the value in the configuration file or by running a command in the shell. Today we saw how our Support Engineers increase the Memcached memory value.
