This technique saves two instructions in the prologue and epilogue and makes one additional general-purpose register (%rbp) available." 2014: Java in Flames Broken Java Stacks (2014) When I joined Netflix in 2014, I found Java's lack of frame pointer support broke all application stacks (pictured in my 2014 Surge talk on the right).

There's no Java stack—there should be a tower of green Java methods—instead there's only a single green frame or two. This is how Java flame graphs looked at the time. Later that year I prototyped the c2 frame pointer fix that became -XX:+PreserveFramePointer, which fixes Java stacks in these profiles.

HammerDB is a software application for database benchmarking. Databases are highly sophisticated software, and to design and run a fair benchmark workload is a complex undertaking. The Transaction Processing Performance Council (TPC) was founded to bring standards to database benchmarking, and the history of the TPC can be found here.

An open-source benchmark suite for microservices and their hardware-software implications for cloud & edge systems Gan et al., It’s a pretty impressive effort to pull together and make available in open source (not yet available as I write this) such a suite, and I’m sure explains much of the long list of 24 authors on this paper.

This has led to the recent release of our new Lambda monitoring extension supporting Node.js, Java, and Python. To handle N parallel requests, N Lambda instances need to be available, and AWS will spin up up to 1000 such instances automatically to handle 1000 parallel requests. Dynatrace has offered a Lambda code module for Node.js

It's challenging for teams climbing the maturity ladder to sift through the many available browser and tool-vendor data points to understand which ones to measure and manage. They are charting a course based on better information because they are cognizant that it is both valuable and potentially available. but against what baseline?

We changed deployment in the middle of the week for both work-life balance and also this way we would have all engineers available in case release runs into an issue.
