Light-4J
A fast, lightweight and more productive microservices framework
...In 2014, I realized that the IT industry was moving from Monolithic to Microservices and from on-premise data centers to the public clouds. To reduce the production cost for my applications, I need to find a lightweight platform that has a small memory footprint, high throughput, and low latency in Java. Java EE and Spring/Spring Boot are too heavy to be considered. Other lightweight Java platforms all have different issues on the separation between the business logic and technical cross-cutting concerns. Moreover, they are not cloud-native or designed for container/cloud. -

LMAX Disruptor
High performance inter-thread messaging library
LMAX aims to be the fastest trading platform in the world. Clearly, in order to achieve this we needed to do something special to achieve very low-latency and high-throughput with our Java platform. Performance testing showed that using queues to pass data between stages of the system was introducing latency, so we focused on optimising this area. The Disruptor is the result of our research and testing. We found that cache misses at the CPU-level, and locks requiring kernel arbitration are both extremely costly, so we created a framework which has "mechanical sympathy" for the hardware it’s running on, and that’s lock-free. ... -

Volley
HTTP library that makes networking for Android apps
...Out of the box it supports JSON, string, and image requests, plus an extensible Request/Response model for custom payloads. Volley emphasizes responsiveness: transparent caching and de-duplication of in-flight requests help reduce latency and bandwidth usage. Error handling, retries with backoff, and request prioritization are first-class, making it easier to handle flaky mobile networks. While Android has other HTTP stacks, Volley’s value is in opinionated, high-level primitives that fit common app patterns without pulling in heavy dependencies. -
