Memcache(d) vs. Varnish for speeding up 3 tier web architecture
Varnish is in front of the webserver; it works as a reverse http proxy that caches. You can use both. Mostly write — Varnish will need to have affected pages purged. This will result in an overhead and little benefit for modified pages. Mostly read — Varnish will probably cover most of it. Similar read … Read more
Memcache Vs. Memcached [duplicate]
They are not identical. Memcache is older but it has some limitations. I was using just fine in my application until I realized you can’t store literal FALSE in cache. Value FALSE returned from the cache is the same as FALSE returned when a value is not found in the cache. There is no way … Read more
How well do nginx and memcached work together?
You really should use a cache server in front of your web servers. I recommend Varnish-cache. We use it at work with the largest and busiest website in scandinavia. We replaced 13 highly loaded Squid boxes with 1 Varnish box, and 1 for spare. I benchmarked a simple app on my private website, and it … Read more

Memcache basic configuration
You did not tell us about your OS/distro. Also, you did not tell us how you installed memcached. Usually, you will get a sample config file under /etc/ when you install memcached using apt-get under debian-based systems and rpm or yum under redhat, fedora or centos.

Memcached vs APC which one should I choose? [closed]
Memcached is a distributed caching system, whereas APC is non-distributed – and mainly an opcode cache. If (and only if) you have a web application which has to live on different webservers (loadbalancing), you have to use memcache for distributed caching. If not, just stick to APC and its cache. You should always use an … Read more
