All Indian Reprints of O'Reilly are Printed in Grayscale.With technological advancements, fast markets, and higher complexity of systems, software engineers tend to skip the uncomfortable topic of software efficiency. However, tactical, observability-driven performance optimizations are vital for every product to save money and ensure business success.With this book, any engineer can learn how to approach software efficiency effectively, professionally, and without stress. Author Bart?omiej P?otka provides the tools and knowledge required to make your systems faster and less resource-hungry. Efficient Go guides you in achieving better day-to-day efficiency using Go. In addition, most content is language-agnostic, allowing you to bring small but effective habits to your programming or product management cycles.This book shows you how to:
Clarify and negotiate efficiency goals
Optimize efficiency on various levels
Use common resources like CPU and memory effectively
Assess efficiency using observability signals like metrics, logging, tracing, and (continuous) profiling via open source projects like Prometheus, Jaeger, and Parca
Apply tools like go test , pprof , benchstat , and k6 to create reliable micro and macro benchmarks
Efficiently use Go and its features like slices, generics, goroutines, allocation semantics, garbage collection, and more!
About the AuthorBartlomiej Plotka is a Principal Software Engineer at Red Hat with a background in SRE. Working primarily on observability topics, he helped to build many popular, reliable, performance, and efficiency-oriented distributed systems in Go. He is a core maintainer of various open-source projects including the CNCF Prometheus (https://prometheus.io/), libraries in the gRPC ecosystem, and more. In 2017 he created, together with Fabian Reinartz, a popular, open source distributed time series database. Focused on cheap and efficient metric monitoring, written in Go and called Thanos (http://thanos.io/), it went through hundreds of performance and efficiency focused improvements and researches. Developing in Go since 2014, BartekÃ??s passion was always to focus on the readability, reliability, and efficiency aspect of the language. On the way, Bartek helped to develop many tools, blog posts and even created opinionated Go code style to teach others on writing pragmatic, but efficient Go applications.

Comfortable Water‑Repellent Summer Shorts That Still Look Casual and Neat
Size: XX-Large, Color: Dark Grey
I find these TACVASEN 7 Inch Casual Twill Shorts very comfortable to wear for warm weather. The polyester twill fabric feels light against the skin and does not trap heat, which makes them a good option for summer days or humid climates. The material also behaves like a water‑repellent, quick‑dry fabric, so light splashes or a bit of sweat do not linger long, and the shorts dry fairly fast instead of staying damp. The overall look is more refined than basic athletic shorts, which I appreciate. The 7‑inch inseam, flat front style, and elastic waistband with drawstring give them a casual, everyday look that can still pass for more polished casual wear if you pair them with a polo or a clean t‑shirt. They do not look sloppy, so they work for running errands, casual outings, or relaxed social situations, not just for the beach or lounging. In terms of construction, the stitching on my pair is nicely done, with no loose threads or obvious defects on the seams or hems. The shorts include two slant pockets and one back pocket, and one of the front pockets has a hidden zipper pocket inside, which is handy for keeping small items like cards or coins more secure without changing the outside look of the shorts. The elastic waistband and drawstring make it easy to dial in the fit without feeling tight. Based on my experience, these shorts would be suitable for a variety of uses such as casual walks, light outdoor activities, beach days, or as comfortable everyday summer shorts that still look presentable enough for casual gatherings. If you want something breathable, quick drying, and a bit more polished than pure gym shorts, these are a solid option. I received this item for free through the Amazon Vine program and I personally evaluate what I receive. I also pay taxes, Social Security and Medicare so I do not treat this as mindless ordering of products I will not use or fully test.

Perfect Summer Shorts for Everyday Wear
Size: Large, Color: Dark Grey
These turned out to be one of those purchases that will become part of the regular summer rotation. The fit is excellent, the fabric feels lightweight without feeling cheap, and they’re extremely comfortable in warm weather. What I like most is that they strike a really nice balance between casual and polished. They don’t look like gym shorts, but they’re just as comfortable. The dark grey color looks clean and versatile, and the 7-inch length feels modern without being overly short. The fabric has a smooth, cool feel and dries quickly, which is great for hot days or even light water exposure. The elastic waistband and drawstring are comfortable without looking sloppy, and the hidden zipper pocket is actually very useful for keys or cards. Another thing I noticed is their durability that they hold their shape well and the material doesn’t wrinkle easily. They work equally well for relaxing, walking around town, travel, or casual dinners outside during summer. Overall, these feel more expensive than they are. Comfortable, lightweight material, practical, and surprisingly stylish.

Fast drying polyester short for casual wear or to use at the beach
Size: Small, Color: Army Green, Size: Small, Color: Army Green
The TACVASEN men's 7" casual beach shorts are lightweight stretchy polyester shorts featuring an elastic waist band for added comfort. These shorts are nicely constructed and durable with no visible signs of defects out of the package. These shorts wear and feel comfortable for all types of activities or for just casual wear if you just want to lounge around. There are two average sized pockets one on each side and one zippered side pocket for added security and a rear pocket suitable for a normal sized wallet. I'm a 5'10" man and these shorts reach to the top of my knee. These shorts also have an average sized drawstring for added tightness if desired. The polyester material allows for fast drying. Overall these shorts offer a good value for wearing to most occasions.

Great casual shorts
Size: Small, Color: Blue Gray
These men’s water-resistant beach shorts have been a great purchase. I got them for my son, and he says they’re extremely comfortable. He especially loves how soft the material feels, which makes them easy to wear all day at the beach, pool, or just casually around town. The water-resistant fabric works well and dries quickly, which is a huge plus for swimwear. They fit nicely and allow for plenty of movement without feeling stiff or heavy. Overall, these are comfortable, well-made shorts with great material, and my son has been really happy with them.

Nice shorts but no fly
Size: Medium, Color: Blue Gray, Size: Medium, Color: Blue Gray
These shorts are well made with three pockets on the sides, 2 standard and one zippered, along with one pocket on the back. They are made of a polyester fabric and do feel as though they will be waterproof. They are well constructed and should hold up well. My issue with these shorts is that they have no fly, just fake stiching on the front. Yes, they say they are for the beach, but that is no reason not to have a fly. Swim trunks are one thing, no one expects a fly on them, but on shorts, yes I do. I always like to include a picture of the laundry instructions,, I hate getting something and discovering it takes special care.
