It was – like the hypothetical movie I describe above – more than a little bit odd, as you could leave a session discussing ever more abstract layers of virtualization and walk into one where they emphasized the critical importance of pinning a network interface to a specific VM for optimal performance.

Containerized data workloads running on Kubernetes offer several advantages over traditional virtual machine/bare metal based data workloads including but not limited to. direct access to raw block storage [18] without the abstraction of a filesystem for workloads that require consistent I/O performance and low latency. Performance.

This is a complex topic, but to borrow from a recent post , web performance expands access to information and services by reducing latency and variance across interactions in a session, with a particular focus on the tail of the distribution (P75+). Consistent performance matters just as much as low average latency.

As an engineer on a browser team, I'm privy to the blow-by-blow of various performance projects, benchmark fire drills, and the ways performance marketing (deeply) impacts engineering priorities. With each team, benchmarks lost are understood as bugs. All modern browsers are fast, Chromium and Safari/WebKit included. Offscreen Canvas.

For anyone benchmarking MySQL with HammerDB it is important to understand the differences from sysbench workloads as HammerDB is targeted at a testing a different usage model from sysbench. CPUs which need to have their frequency coordinated by software: 0 . maximum transition latency: Cannot determine or is not supported. .

We have spent a great deal of time at ScaleOut Software re-architecting our in-memory data grid (IMDG)’s code base to make best use of many cores and large memory. Likewise, object access paths must be heavily multi-threaded and avoid lock contention to minimize access latency and maximize throughput. Testing Scale-Up Performance.

The caching of data pages and grouping of log records helps remove much, if not all, of the command latency associated with a write operation. ​​ The following table outlines the virtual protection states. Page State Virtual Protection State Dirty Read Write ​​ during the modification.

Many high-end disk subsystems provide high-speed cache facilities to reduce the latency of read and write operations. Mirroring can be implemented at a software or hardware level. Dirty Page Latency ​​ – A page is considered dirty when data modifications have taken place.

Estimated Input Latency tells us if we are hitting that threshold, and ideally, it should be below 50ms. Designed for the modern web, it responds to actual congestion, rather than packet loss like TCP does, it is significantly faster , with higher throughput and lower latency — and the algorithm works differently.
