memory-stats.js - minimal monitor for JS Heap Size via performance.memory

•    Javascript

---

@jeromeetienne, inspired by mrdoob's stats.js code, wrote this as part of tquery. I've now promoted it to a standalone repo and cleaned it all up. Run Chrome with the flag and open demo/index.html to see it in action.

space-radar - Disk And Memory Space Visualization App built with Electron & d3.js

•    Javascript

---

SpaceRadar allows interactive visualization of disk space and memory. It currently supports Sunburst, Treemap, and Flamegraph charts. Compressed files can be read directly. To detect them, the file name has to end with .gz.

thegreatsuspender - A chrome extension for suspending all tabs to free up memory

•    Javascript

---

Please contribute if you have any extra insight on alternative methods for tab recovery. "The Great Suspender" is a free and open-source Google Chrome extension for people who find that chrome is consuming too much system resource or suffer from frequent chrome crashing. Once installed and enabled, this extension will automatically suspend tabs that have not been used for a while, freeing up memory and cpu that the tab was consuming.

ps_mem - A utility to accurately report the in core memory usage for a program

•    Python

---

Yes the name is a bit weird. coremem would be more appropriate, but for backwards compatible reasons the ps_mem name remains. pip install ps_mem is supported, or rpm and deb packages are available for most distros. Also the ps_mem.py script can be run directly.

scalloc - A Fast, Multicore-Scalable, Low-Fragmentation Memory Allocator

•    C++

---

scalloc provides general-purpose memory allocation involving many threads on many cores can be done with high performance, multicore scalability, and low memory consumption. The main ideas behind the design of scalloc are: uniform treatment of small and big objects through so-called virtual spans, efficiently and effectively reclaiming free memory through fast and scalable global data structures.

memguard - Easy and secure handling of sensitive memory, in pure Go.

•    Go

---

A pure Go library that handles sensitive values in memory.This is a thread-safe package, designed to allow you to easily handle sensitive values in memory. It supports all major operating systems and is written in pure Go.

Apache Mnemonic - Non-volatile hybrid memory storage oriented library

•    Java

---

Apache Mnemonic is a non-volatile hybrid memory storage oriented library, it proposed a non-volatile/durable Java object model and durable computing service that bring several advantages to significantly improve the performance of massive real-time data processing/analytics. developers are able to use this library to design their cache-less and SerDe-less high performance applications.

rpmalloc - Public domain cross platform lock free thread caching 32-byte aligned memory allocator implemented in C

•    C

---

The code should be easily portable to any platform with atomic operations and an mmap-style virtual memory management API. The API used to map/unmap memory pages can be configured in runtime to a custom implementation and mapping granularity/size. This library is put in the public domain; you can redistribute it and/or modify it without any restrictions. Or, if you choose, you can use it under the MIT license.

nodecache - a node internal caching module

•    CoffeeScript

---

A simple caching module that has set, get and delete methods and works a little bit like memcached. Keys can have a timeout (ttl) after which they expire and are deleted from the cache. All keys are stored in a single object so the practical limit is at around 1m keys. Since 4.1.0: Key-validation: The keys can be given as either string or number, but are casted to a string internally anyway. All other types will either throw an error or call the callback with an error.

apicache - Simple API-caching middleware for Express/Node.

•    Javascript

---

Because route-caching of simple data/responses should ALSO be simple. To use, simply inject the middleware (example: apicache.middleware('5 minutes', [optionalMiddlewareToggle])) into your routes. Everything else is automagic.

jemalloc - Scalable, Concurrent, Malloc Implementation

•    C

---

jemalloc is a general purpose malloc(3) implementation that emphasizes fragmentation avoidance and scalable concurrency support. It is intended for use as the system-provided memory allocator, as in FreeBSD's libc library, as well as for linking into C/C++ applications. jemalloc provides many introspection, memory management, and tuning features beyond the standard allocator functionality.
