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

DZone

This begins not only in designing the algorithm or coming out with efficient and robust architecture but right onto the choice of programming language. One, by researching on the Internet; Two, by developing small programs and benchmarking. Most of us, as we spend years in our jobs — tend to be proficient in at least one of these.

The Return of the Frame Pointers

Brendan Gregg

It was also a virtual machine that lacked low-level hardware profiling capabilities, so I wasn't able to do cycle analysis to confirm that the 10% was entirely frame pointer-based. Google should be no surprise because they pioneered continuous profiling.) The actual overhead depends on your workload. Back-end servers.

From Heavy Metal to Irrational Exuberance

ACM Sigarch

To be clear, these languages were not designed to be fast or space-efficient, but for ease of use. Unfortunately, languages like Python have proven resistant to efficient implementation, partly because of their design, and partly because of limitations imposed by the need to interop with C code. As Leiserson et al.

Compress objects, not cache lines: an object-based compressed memory hierarchy

The Morning Paper

Last time out we saw how Google have been able to save millions of dollars though memory compression enabled via zswap. One of the important attributes of their design was easy and rapid deployment across an existing fleet. Consider a B-Tree node from the B-tree Java benchmark: Uncompressed, it’s memory layout looks like (a) below.

Progress Delayed Is Progress Denied

Alex Russell

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. PowerPoint or Google Slides). This is as it should be. Trusted Types.

The Performance Inequality Gap, 2021

Alex Russell

Hardware Past As Performance Prologue. Using a global ASP as a benchmark can further mislead thanks to the distorting effect of ultra-high-end prices rising while shipment volumes stagnate. Chip design choices and silicon economics are the defining feature of the still-growing Performance Inequality Gap. Mind The Gap.
