The plugins benchmarking project being conducted on Dev4Press primarily uses their plugin GD Press Tools.

That link is to the 'lite' version, on the official WordPress Extend Repository. But the Pro version is probably different, mainly in offering better support for multisite, and incuding features of use in commercialized WordPress activities.

I will be using the standard version, following along with Milan's post & tutorial, practicing the techniques shown, and noting any differences with the Pro version, for the purposes of benchmarking plugins.

I also have installed a collection of other plugins which individually achieve parts & pieces of what Milan has done with GD Press Tools. Some of these (also) involve a more or less demanding learning curve, while others are simply 'constructive eye-candy', eg Info.
