Sphinx 2.0.1 brings with it the ability to call UPDATE and update an individual item in an index.

Does anyone know what type of performance this brings to sphinx when called VERY frequently (as frequently as several hundred times a second)? The reason for this would be to keep a real time index of trending item scores which get updated every time a user performs an action. Obviously when there are lots of users this value can be update quite frequently.

**EDIT:**

I should mention that I am not using SphinxSE.
