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

This begins not only in designing the algorithm or coming out with efficient and robust architecture but right onto the choice of programming language. Recently, I spent some time checking on the Performance (not a very detailed study) of the various programming languages.

What programming languages does HammerDB use and why does it matter?

HammerDB

FEBRUARY 25, 2021

HammerDB is a load testing and benchmarking application for relational databases. However, it is crucial that the benchmarking application does not have inherent bottlenecks that artificially limits the scalability of the database. This is why the choice of programming language is so important from the outset.

Crucial Redis Monitoring Metrics You Must Watch

Scalegrid

JANUARY 25, 2024

Key metrics like throughput, request latency, and memory utilization are essential for assessing Redis health, with tools like the MONITOR command and Redis-benchmark for latency and throughput analysis and MEMORY USAGE/STATS commands for evaluating memory. All these contribute significantly towards ensuring smooth functioning.

Faster remainders when the divisor is a constant: beating compilers and libdivide

Daniel Lemire

FEBRUARY 8, 2019

The division by a power of two ( / (2 N )) can be implemented as a right shift if we are working with unsigned integers, which compiles to single instruction: that is possible because the underlying hardware uses a base 2. We also published our benchmarks for research purposes. I make my benchmarking code available.

In fact, according to Stack Overflow’s annual developer survey , JavaScript and Python are now the #1 and #2 most used programming languages, respectively (excluding HTML/CSS and SQL as “programming languages”). To be clear, these languages were not designed to be fast or space-efficient, but for ease of use.

HammerDB for Managers

HammerDB

JUNE 27, 2022

HammerDB is a software application for database benchmarking. It enables the user to measure database performance and make comparative judgements about database hardware and software. Databases are highly sophisticated software, and to design and run a fair benchmark workload is a complex undertaking. Adoption by the TPC.

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

The Morning Paper

MAY 23, 2019

These techniques work well for scientific programs that are dominated by arrays. However, they are ineffective on object-based programs because objects do not fall neatly into fixed-size blocks and have a more irregular layout. Consider a B-Tree node from the B-tree Java benchmark: Uncompressed, it’s memory layout looks like (a) below.

Machine learning systems are stuck in a rut

The Morning Paper

JUNE 27, 2019

Systems researchers are doing an excellent job improving the performance of 5-year old benchmarks, but gradually making it harder to explore innovative machine learning research ideas. Convolutional Capsule primitives can be implemented reasonably efficiently on CPU but problems arise on accelerators (e.g. GPU and TPU).

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. Provides support for "unread counts", e.g. for email and chat programs.

Looking Ahead Beyond CMOS

ACM Sigarch

OCTOBER 25, 2018

Studies have demonstrated that current generation OOO architectures extract significantly less ILP than is available in the programs. These cellular neural network circuits may be used to create efficient convolution neural networks (CNNs) used in deep-learning applications, and fundamentally change the way we design AI processors.

A peculiar throughput limitation on Intel’s Xeon Phi x200 (Knights Landing)

John McCalpin

JANUARY 22, 2018

Hardware performance counter results for a simple benchmark code calling Intel’s optimized DGEMM implementation for this processor (from the Intel MKL library) show that about 20% of the dynamic instruction count consists of instructions that are not packed SIMD operations (i.e., addl $1, %eax vfmadd213pd %zmm16, %zmm17, %zmm29.

The Performance Inequality Gap, 2024

HTML, CSS, images, and fonts can all be parsed and run at near wire speeds on low-end hardware, but JavaScript is at least three times more expensive, byte-for-byte. Front-end developers are cursed to program the Devil's computer. Those folks may not find the next couple of years to their liking.
