Memcached Vs. MySQL

Some interesting observations about Memcached Vs. MySQL over on the StyleFeeder Tech Blog.

I think the lack of good benchmarks prevent anyone from making a definitive statement on the matter. Each system will be different and there will be cases where memcached is a good thing, cases where memcached does not bring anything to the table, and cases where memcached is just play hurtful. What it really comes down to is this: “Just how fast can you get data out of your database,” which is really just a way of rephrasing the age-old question: “Do you know where your bottlenecks are.”

To me memcached is another moving part which requires administration and maintenance. If you can do without it, great! But if your site benefits from it then by all means use it.
