XanMod is a Linux-based kernel with custom modifications aiming to "take full advantage in high-performance workstations, gaming desktops, media centers and others." XanMod is primarily geared for Debian/Ubuntu systems but obviously could work elsewhere.
The XanMod kernel uses the BFS scheduler, BFQ I/O scheduler, UKSM realtime memory data deduplication, YeAH TCP congestion control, x86_64 advanced instruction set support, and other default changes.
As some quick tests, I ran the XanMod latest kernel (also is 4.3 based at the time of testing) compared to my other mainline Linux kernel and Liquorix results from this weekend. With those benchmarks, they may not be best suited for showing the potential performance changes of this kernel, but were just what I had available with my limited time and resources.
If you want to see how the current XanMod kernel compares to other Linux 4.3/4.4 kernels, go check out this OpenBenchmarking.org result file for all of the initial data. If there's enough interest (particularly among Phoronix Premium members), more investigating and tests will take place in due time.
