Hello LET,
I'm in the progress of compiling some linux kernels for my KVM LEBs with grsecurity; When it comes to optimizations however, I am quite clueless as to what should be done and there aren't much resources out there...
What are some tricks/optimizations that you usually do, and why do you do it (benefits for websites, etc)? eg. enable tickless system (dynamic ticks) for game server hosting.
Edit: Also, outside of the kernel, it'll be interesting to see what I/O scheduler fits best for your use case. (CFQ/anticipatory/deadline/noop)
It'll be interesting to see what tricks everyone has up their sleeves.
