Hello!
We had an earlier discussion about using real-time policies on modern CPUs for cpu-bound tasks with "near real-time" execution time expectations (like front-end servers): https://lkml.org/lkml/2014/4/24/602 .
I sad, that I had a prototype of real-time load balancer (called smart), that performs well in this case.
Now it's ready to be published.
The patch set on top of the 3.10.x branch can be found here: https://github.com/yandex/smart .
It's stable. We use them in production for a couple of months on more than thousand machines. We get noticeable performance increase for many projects with different load patterns (up to 10-15% in both RPS and latency).
Any feedback, comments, questions are welcome!
Regards, Roman
