Newest Linux Optimizations Can Achieve 10M IOPS Per-Core With IO_uring

Just one week ago Linux block subsystem maintainer Jens Axboe was optimizing the kernel to get 8 million IOPS on a single CPU core. He progressed the week hitting around ~8.9M IOPS per-core and began to think he was hitting the hardware limits and running out of possible optimizations. However, this week he is kicking things off by managing to hit 10 million IOPS!..

Dynatron A39 – A Good Heatsink For Threadripper/EPYC 4U Systems

Quietly released earlier this year was the Dynatron A39 heatsink that is capable of up to 280 Watts heat dissipation for satisfying even the very latest, high-end AMD EPYC 7003 “Milan” processors. This Dynatron A39 TR4/sTRX4/SP3 heatsink has been working out very well for those needing to cool a Threadripper/EPYC system in a 3U or larger enclosure.
