My last talk for 2017 was at AWS re:Invent, on "How Netflix Tunes EC2 Instances for Performance," an updated version of my [2014] talk. A video of the talk is on youtube : The slides are on slideshare : I love this talk as I get to share more about what the Performance and Operating Systems team at Netflix does, rather than just my work.

The success of our early results with the Dynamo database encouraged us to write Amazon's Dynamo whitepaper and share it at the 2007 ACM Symposium on Operating Systems Principles (SOSP conference), so that others in the industry could benefit. This was the genesis of the Amazon Dynamo database.

To benchmark a database we introduce the concept of a Virtual User. For this reason we need to implement our database sessions in the form of operating system threads. So having an application client mutex lock that artificially stalls our Virtual Users does not sound good. Basic Benchmarking Concepts. The Python GIL.

In fact, once containerized, many of these services and the source code itself is virtually invisible in a standalone Kubernetes environment.

Regardless of whether the computing platform to be evaluated is on-prem, containerized, virtualized, or in the cloud, it is crucial to consider several essential factors.

However as noted many factors affect spin-locks including how much time you actually spend in locks in the first place and therefore the best way to really determine how much time you have to spend in fine-tuning spin-locks in the real world can be done through testing.

In this blog post, we will discuss the best practices on the MongoDB ecosystem applied at the Operating System (OS) and MongoDB levels. The main objective of this post is to share my experience over the past years tuning MongoDB and centralize the diverse sources that I crossed in this journey in a unique place.

“ Scalability” is a product of both the benchmarking application itself (See the post on HammerDB Architecture to see how it scales implementing multiple virtual users as threads) as well as the benchmarking workload (The TPC benchmarks that HammerDB uses have been designed specifically for this purpose and proven over decades to scale).

Prior to SQL Server 2012, the maximum server memory value only applied to the bufferpool, so customers needed to limit the amount of memory the bufferpool could use to save memory for the operating system and other processes. It is highly advisable to set a maximum value for your SQL Server instance. SQL Server Agent Alerts.

Many of these systems support I/O ordering with a stable media cache and subsequently combine and/or split I/O requests across available subsystem resources to complete the storing to physical media. For specific information on I/O tuning and balancing, you will find more details in the following document.

I was mostly coding in C, tuning FORTRAN, and when I needed to do a lot of data analysis of benchmark results used the S-PLUS statistics language, that is the predecessor to R. We had specializations in hardware, operating systems, databases, graphics, etc. Rich Pettit is one of the best programmers I ever met.

An official benchmark will not typically be implemented with thousands of connections to the database, instead the connections are managed by the middleware, as HammerDB does with asynchronous scaling where each Virtual User manages a much larger user defined number of connections.
