Which way is better for running memcached?

[Steven Grimm]

We use it a lot. We divide the data for a given page into "stuff we need 
immediately for the business logic that will change what other data we 
need to fetch," "stuff we need for the business logic that we can 
evaluate in isolation," and "stuff we're going to display." The first 
gets fetched as needed during the execution of the page. The second and 
third, we queue up internally and request all in one big "get" just 
before rendering the page at the end of the request; for the second 
class of data, we have a callback mechanism wrapped around the memcached 
client so that we can run our business logic using some of the returned 
data. There are some additional wrinkles but that's the rough idea.

By the way, it's not really any easier or harder in PHP than in any 
other language; it's about application structure, not language. If we 
were writing our site in Java or Python or C/C++ we'd probably do 
exactly the same thing.
