The optimizations that are worth doing are those that affect everything… And if you use memcached, then memcached affects everything In this blog post I present a benchmark of 4 most popular Python memcached libraries (one of them pure Python, the 3 others C wrappers).

As my benchmark shows, there are lots of gains, basically you can speed up your memcached operations by 2x times – which is REALLY hard to do with any other optimization.

There are currently 4 Python memcached libraries and there aren’t any good benchmarks of these, so I have set a goal to benchmark these. The candidates:
