NeteXt’73 is a collection of patches on the latest released Linux kernel for improved performance and power management, currently available for Ubuntu and its derivatives. All the information regarding this development is in Polish so the information we could collect (after seeing the original post about it on Phoronix) is through Google Translate and looking at the source code of the project on GitHub.
The optimizations are around CPU microcode (Intel and AMD64), Linux firmware package and Advanced Power Management. The package provides GUI based tool to tweak several parameters as well as to set your own preferences for these components and the kernel. The modifications have been tested with the famous Phoronix Test Suite and has shown better performance and power savings than the stock kernel.
The source has integrated code to make payments through the Paypal gateway. So it seems that once you make the payment the features will be unlocked. The price is around $15.
To install the packages from PPA:
$ sudo add-apt-repository ppa:netext/netext73 $ sudo apt-get update $ sudo apt-get install netext73
Note that the packages include benchmarking tools as well.
