Performance tuning Twitter services with Graal and Machine Learning

Friday, September 27 – Day 2 - 14:15 - Room 1

Running Twitter services on Graal has been very successful and saved Twitter a lot of money on datacenter cost. But we would like to run more efficient to reduce cost even more. I mean, who doesn’t? In order to do this we are using our Machine Learning framework called Autotune to tuneGraal inlining parameters. This talk will show how much performance improvement we got by autotuning Graal.
