assigning to a specific CPU) is a manageable resource, represented by the concept of “virtual CPU” as a term that includes CPU cores, hyperthreads, hardware threads, and so forth. Then we need to see IF implementing the tuning will work or not. It is possible to do more tuning in the case that ETL is too compromised.

In the simplest case, you have a growing workload, and you optimize it to run more efficiently so that you don’t need to buy or rent additional hardware, so your carbon footprint stays the same, but the carbon per transaction or operation is going down. I’ve written before about how to tune out retry storms.

Serverless computing can be a huge benefit to organizations that don’t have the necessary resources or teams to manage physical resources, like servers/hardware, and all the maintenance and licensing that goes along with that, allowing them to focus on developing their code and applications. Benefits of a Serverless Model.

Since instances of both CentOS and Ubuntu were running in parallel, I could collect flame graphs at the same time (same time-of-day traffic mix) and compare them side by side. As a Xen guest, this profile was gathered using perf(1) and the kernel's software cpu-clock soft interrupts, not the hardware NMI. But I'm not completely sure.

The IBM Z platform is a range of mainframe hardware solutions that are quite frequently used in large computing shops. Typically, these shops run the z/OS operating system, but more recently, it’s not uncommon to see the Z hardware running special versions of Linux distributions. Stay tuned for more announcements on this topic.

Before you begin tuning your website or application, you must first figure out which metrics matter most to your users and establish some achievable benchmarks. Just because everything works perfectly during production testing doesn’t mean that will be the case when your website is flooded with traffic.

Not all back-end errors affect the user experience, but keeping track of them can prove helpful when tuning your app. Monitoring errors on the front-end requires a bit more work because front-end performance is highly dependant on the user’s hardware, software and connection.

Linux has been adding tracing technologies over the years: kprobes (kernel dynamic tracing), uprobes (user-level dynamic tracing), tracepoints (static tracing), and perf_events (profiling and hardware counters). Outside of EC2, many other providers are deploying on KVM. The OS is becoming a forgotten cog in a much larger cloud-based system.

You can download these models to use out of the box, or employ minimal compute resources to fine-tune them for your particular task.

As such, tuning congestion logic is usually only done by a select few developers, and evolution is slow. Many network interface controllers (NICs) even have built-in hardware-offload features for TCP. We can also expect QUIC-specific hardware to become available. Finally convinced?
