At Perform 2021 , Dynatrace’s Kristof Renders, Services Practice Manager for Autonomous Cloud Enablement, joined Sumit Nagal, Principal Engineer at Intuit, to demonstrate how service-level objectives (SLOs) and business-level objectives (BLOs) can “shift left.” For example, improving latency by as little as 0.1

Here begins our 2021 adventure. If there's a bright spot in our construction of a 2021 baseline for performance, this is it. Using a global ASP as a benchmark can further mislead thanks to the distorting effect of ultra-high-end prices rising while shipment volumes stagnate. A 2021 Global Baseline. Hard Reset.

A Cassandra database cluster had switched to Ubuntu and noticed write latency increased by over 30%. I love short benchmarks like this as I can disassemble the resulting binary and ensure that the compiled instructions match my expectations, and the compiler hasen't messed with it. ## 6. include <sys/time.h>

As we said in 2021, " 4G is a miracle, 5G is a mirage." Test Device Recommendations # Re-using last year's P75 device calculus , our estimate is based on a device sold new, unlocked for the mid-2020 to mid-2021 global ASP of ~$350-375. Regulatory roadblocks are still being cleared. 2:1] The A51 featured eight slow cores (4x2.3
