more capable, and built from the ground up for the modern era of the eBPF virtual machine. Since I helped developed bpftrace, I'm aware of how fresh my own code is and how likely I introduced bugs. Created by Alastair Robertson , bpftrace is an open source high-level tracing front-end that lets you analyze systems in custom ways.

The ISO/IEC 9075:2016 standard, or SQL:2016 in short, introduces support for a profound concept called Row Pattern Recognition (RPR) in SQL. I posted a suggestion to improve SQL Server by adding support for RPR in T-SQL , but I was quite limited in the space that I had to provide the feedback. Ticker ; CREATE TABLE dbo.

SQL Server relies on Forced-Unit-Access (Fua) I/O subsystem capabilities to provide data durability, detailed in the following documents: SQL Server 2000 I/O Basic and SQL Server I/O Basics, Chapter 2. Be sure to deploy SQL Server 2017 CU6 or newer for best data durability and performance results. “. The Back Story.

The transaction log contains virtual log files, which contain log blocks, which store the actual log records. Virtual Log Files. The transaction log is split up into sections called virtual log files , commonly just called VLFs. Due to this problem, in SQL Server 2014 the algorithm changed for auto-growth of the log file.

LTS (April 2016). It uses a Solaris Porting Layer (SPL) to provide a Solaris-kernel interface on Linux, so that unmodified ZFS code can execute. There's also a ZFS send/recv code path that should try to use the TASK_INTERRUPTIBLE flag (as suggested by a coworker), to avoid a kernel hang (can't kill -9 the process).

The presence of virtual DOM and SPA are the key influencing USPS of React JS. React developers introduced Inferno in 2016 as an experiment to examine whether or not a library can improve the battery, performance, and UX of mobile apps. You will get add-ons like server-side rendering, routing and more. Inferno Cons.

Teams achieving this level of discipline about performance begin to eliminate variance from their lab data by running tests in "less noisy" environments than somewhere like a developer's laptop, a shared server, or a VM with underlying system variance. miAi3020A9G #perfmatters 1 10:04 AM · Jul 7, 2016.

Correspondingly, 3GB functions should see a 2x CPU performance improvement over 1.5GB Lambdas, but this is through doubling the number of cores the function has access to, rather than double the virtualized time-slices. without web app servers?—?to We plan to test this out when we get the chance. But we’re keeping an open mind.
