Measuring Hyper-Threading and Turbo Boost
Contemporary x86 processors implement some variants of Hyper-Threading and Turbo Boost. We decided to learn about the implications of these two technologies.
Designing Edge Servers with Arm CPUs to Deliver 57% More Performance Per Watt
Using Arm, Cloudflare can now securely process over ten times as many Internet requests for every watt of power consumed, than we did for servers designed in 2013.
ARMs Race: Ampere Altra takes on the AWS Graviton2
A comparison between the Ampere Altra and the AWS Graviton2, the two ARM Neoverse N1-based processors.
Gen X Performance Tuning
We have partnered with AMD to get the best performance out of this processor and today, we are highlighting our tuning efforts that led to an additional 6% performance. Thermal design power (TDP) and dynamic power, amongst others, play a critical role when tuning a system.
Impact of Cache Locality
Our Gen X servers process more requests per second per core than our previous fleet. The AMD 2nd Gen EPYC 7642 processor’s large L3 cache minimizes L3 cache misses, and the time-savings add up quickly.
