The Return of the Frame Pointers

Brendan Gregg

I'm sure this delivered large performance improvements and I wouldn't try arguing against it. While that Java change led to discovering countless performance wins in application code, libc was still breaking some portion of the samples (as pictured in the example at the top of this post) and preventing off-CPU flame graphs.

An analysis of performance evolution of Linux’s core operations

The Morning Paper

An analysis of performance evolution of Linux’s core operations Ren et al., For example: “Red Hat and Suse normally required 6-18 months to optimise the performance an an upstream Linux kernel before it can be released as an enterprise distribution”, and. Google’s data center kernel is carefully performance tuned for their workloads.

SKP's Java/Java EE Gotchas: Clash of the Titans, C++ vs. Java!

DZone

As a Software Engineer, the mind is trained to seek optimizations in every aspect of development and ooze out every bit of available CPU Resource to deliver a performing application. Recently, I spent some time checking on the Performance (not a very detailed study) of the various programming languages. Ahem, Slow!

The Performance Inequality Gap, 2024

Alex Russell

The usual caveats also apply: Performance is a deep and nuanced domain, and much can go wrong beyond content size and composition. How sites manage resources after-load can have a big impact on perceived performance. Until and unless teams have better data about their performance, the global baseline budget should be enforced.

Ten years of page bloat: What have we learned?

Speed Curve

If you've been working in the performance space for a while and you hear me start to talk about page growth, I'd forgive you if you started running away. ;). How does page bloat affect other metrics, such as Google's Core Web Vitals? Image size is another issue, as excessive image weight hurts your SEO ranking in Google Image Search.

The Performance Inequality Gap, 2021

Alex Russell

Back in 2016, I gave a talk outlining the causes and effects of the terrible performance of web apps built using popular tools on the fastest-growing device segment: low-end to mid-range Android phones. Poor performance has a compound effect on user expectations at an ecosystem level. Live by the link, die by the link.

From Heavy Metal to Irrational Exuberance

ACM Sigarch

The focus of most published research in architecture is on applications implemented in high-performance, “ close-to-the-metal” languages essentially developed before computers got fast. The current state-of-the-art Python compiler, pypy , often yields around a 2x improvement in performance (and sometimes less).
