For awhile, I offered 3 distinct flavours of the kernel, one for low latency systems, one for batch workloads, and then one for everyone else. Fast forward to today, it's a single kernel again, but this time optimized for all 3 types of workloads on x86_64 hardware with Fedora 20 (or anything able to use a Fedora kernel without any special requirements, all you need is the build environment and dracut to build the initramfs needed by the kernel.). I've focused on security and speed (in that order actually) over ease of use as the included install script is hand made for my specific install instructions for that kernel release so that all you need to know is how to start the script and what your root password is. It also ships with zRAM enabled and the control scripts are included to allow you to extract a little more performance from your system. zRAM is also great for SSD users as it's swap priority is higher than flash backed swap so that it minimizes the number of writes to the drive, normal HDDs benefit as well due to the fact they're not waiting for the disk, the CPU merely needs to decompress the data that's in memory. On my Intel Core i5 3337U CPU, the decompression isn't even noticeable, the worst case I've seen personally is that the kernel loses it's low latency edge over the stock Fedora kernel (3.12.8-300.fc20.x86_64 vs 3.12.8-cfyffe-2014.01.25-RELEASE).... read more

Added the Tuxonice patch to the 20131230 patch, this brings me to having BFS, BFQ, and my patch for cpufreq_conservative. I plan to make it so my own patches I create myself are seperated from the others in another set of patches, but that's to be done later. I'm too busy setting up git to do so now.
