It’s fairly simple. You write values using keys and expiry times. You get values using keys. You can expire keys from the system. Most clients follow the same rules. You can read the generic instructions and best practices on the memcached homepage. If you really want to dig into it, I’d look at the source. … Read more
MAC Users You can do it easily using brew. brew install autoconf
Using root, try something like this: /etc/init.d/memcached restart
I know this is an older question, but I wanted to post an answer for users with the same question: curl -H ‘Cache-Control: no-cache’ http://www.example.com This curl command servers in its header request to return non-cached data from the web server.
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
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
Found a way, thanks to the link here (with the original google group discussion here) First, Telnet to your server: telnet 127.0.0.1 11211 Next, list the items to get the slab ids: stats items STAT items:3:number 1 STAT items:3:age 498 STAT items:22:number 1 STAT items:22:age 498 END The first number after ‘items’ is the slab … Read more
I have 10.8 installed and Xcode 4.4 with Command Line tools, and yet I was still getting this error. Rather than reinstall Xcode, I noticed there were two relevant lines in my config.log: configure:5130: checking for C compiler version configure:5139: /Applications/Xcode.app/Contents/Developer/Toolchains/OSX10.8.xctoolchain/usr/bin/cc –version >&5 That path did not exist for me. Instead I had: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain The … Read more
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
Depends on what you need, in general I think that: You should not care too much about performances. Redis is faster per core with small values, but memcached is able to use multiple cores with a single executable and TCP port without help from the client. Also memcached is faster with big values in the … Read more
