It enables the user to measure database performance and make comparative judgements about database hardware and software. Databases are highly sophisticated software, and to design and run a fair benchmark workload is a complex undertaking. HammerDB has graphical and command line interfaces for the Windows and Linux operating systems.

So, when designing Amazon SageMaker we took on a challenge: to build machine learning algorithms that can handle an infinite amount of data. This post lifts the veil on some of the scientific, system design, and engineering decisions we made along the way. What does that even mean though? This sounds like a pipe dream.

Hadoop’s value—being able to crunch large datasets—often paled in comparison to its costs. Doubly so as hardware improved, eating away at the lower end of Hadoop-worthy work. Google goes a step further in offering compute instances with its specialized TPU hardware. The elephant was unstoppable. Until it wasn’t.

The approach was influential in the design of the SQL Sentry performance dashboard, which presents waits flanked by queues (key resource metrics) to deliver a comprehensive view of server performance. It doesn't lend itself to easy comparison or correlation, especially when SQL Server is on a VM that lives on an over-subscribed host.

The goal is to produce a low-energy hardware classifier for embedded applications doing local processing of sensor data. Race logic has four primary operations that are easy to implement in hardware: MAX, MIN, ADD-CONSTANT, and INHIBIT. One efficient way of doing that in analog hardware is the use of current-starved inverters.

One aspect of performance is about how efficiently a transport protocol can use a network’s full (physical) bandwidth (i.e. While this is conceptually possible (QUIC does exactly that), things were initially not designed like this, because we need to be able to use TCP with and without TLS on top.
