rwasa High Performance Web Server Claiming to be Better than nginx and lighttpd

2 Ton Digital – a company which provides products, services and support for any company or individual that is interested in security, network performance, website speed and hardware efficiency – is claiming that they have made a web server called rwasa which is faster than nginx and lighttpd.

Rwasa is build using 2 Ton Digital’s HeavyThing Library toolkit. It is a high-performance web server with specific focus on performance across the board, and a TLS (security) performance increase over otherOpenSSL servers. It is a drop-in replacement to nginx and many other web servers. Being hand written with assembly language, cryptography has given rwasa a significant speed and efficiency increase. Unlike other servers, rwasaincludes function hooks (ready made to facilitate Rapid Web Application Server in Assembler development) to allow custom programming at the web server level along with direct manipulation of web requests and responses.

Assembly language is the most “basic” programming language and requires the highest level of technical proficiency. This is because assembly language code is written per the actual CPU manufacturers instructions, i.e. an assembly language instruction in most cases corresponds directly to a physical CPU instruction. This allows programmers to write code that is faster and more efficient than any other language used today, because all higher-level languages must eventually be composed into assembly language itself. But, with all these writing code in assembly language is very complicated and that’s why high-level languages have dominated the market. 2 Ton Digital’s has made a toolkit called HeavyThing Library for building and modifying code in assembly language easier and more efficient than ever before.

Coming back to rwasa- it is a full-featured, high-performance, scalable web server designed to compete with the likes of nginx. It has been built from the ground-up with no external library dependencies entirely in x86_64 assembly language, and is the result of many years’ experience with high volume web environments.

Let’s look at the concrete features of rwasa-

• Open source/GPLv3
• Entirety hand-written in x86_64 assembly language
• Faster than nginx for most environments
• Commercial support available
• TLS auto-blacklisting for anti-tampering
• OCSP Stapling by default
• Randomized Diffie-Hellman safe prime pool
• Multi-process lockless TLS session resumption cache
• TLS session cache is encrypted by default
• Faster dynamic content compression
• Large-scale FastCGI safely via unix sockets (without hitting EAGAIN)
• Large-scale backpath (aka upstream) safely via unix sockets
• Simple command-line arguments covers all common configurations
• Small footprint, no external dependencies
• Server-side BREACH mitigation
• HSTS enabled by default

Following are the results of performance test with nginx and lighttpd. Below graph shows the raw requests per second handling per-CPU of each web server with

No TLS, localhost, flat out

Raw requests per second handling per-CPU of each web server – No TLS, localhost, flat out

TLS, RSA 2048 bit keys

Raw requests per second handling per-CPU of each web server – TLS, RSA 2048 bit keys

TLS, RSA 4096 bit keys

Raw requests per second handling per-CPU of each web server – TLS, RSA 4096 bit keys

Looking at the performance benchmark it surely looks like rwasa is outperforming nginx and lighttpd. I am hoping if developers are ready to adapt it, there will be a huge improvement on web server response time altogether.

With the ever advancing technology, the modes of warfare have also developed with time to become more sophisticated. The countries are not just banking upon their defense officers and soldiers to protect them or win a battle when comes the situation, but they also are testing and developing high-end superweapons to give them an advantage, and also reduce casualties. Recently, US Military came into limelight when they signed a deal with Malloy Aeronautics for a new class of Tactical Reconnaissance Vehicle (TRV).

This time it is Russia that has claimed of a revolutionary superweapon that has the capability to dilapidate enemies’ satellites and the cruise weapons guided by them. It is a means of a modern electronic warfare that causes less human destruction compared to earlier means. This weapon has the potential to shut down all the satellite-based radio-electronic equipment of the target.

The new system is being developed by Russia’s Radio-Electronic Technologies Group (KRET) and it complies with the International Weapons Law, means it won’t be mounted on the satellites, but would be used from the ground, air, and sea.

The Russian superweapon can completely mute all the communications, navigation, and other satellite-guided precision missiles. Basically it could just ‘Switch Off’ the enemy satellites, thus making their sophisticated weapons useless.

Currently, the weapon is ongoing ground testing and will be taken out for trials at testing ranges later this year. With efforts from various countries and organizations to get Nuclear Weapons banished across the world, are we looking at the more advanced Electronic Warfare; could this new system really be Russia’s Superweapon against the world?

open source at twitter

Welcome to the second post of the series covering top open source projects by most popular companies in the world. Last time, we covered Facebook’s contribution to open source communityand in this article, we are going to highlight most popular open source projects made by twitter engineering team.

Twitter engineers use, contribute to and release a lot of open source software and their GitHub repo is a proof of that. Twitter has 131 public repos, maintained by 116 active twitter members around the globe. Twitter as such started as a simple Ruby on Rails application but soon realized that – to meet the scale demand of twitter, they need to re-invent and revamp the entire platform. And while doing that, they had implemented and open sourced many great projects. Twitter also maintains an open source community Twitter handle @TwitterOSS.

Top Twitter open source projects are:

Scalding

Scalding is a Scala library that makes it easy to specify Hadoop MapReduce jobs. Scalding is built on top of Cascading, a Java library that abstracts away low-level Hadoop details. Scalding is comparable to Pig, but offers tight integration with Scala, bringing advantages of Scala to your MapReduce jobs.

Finagle

Finagle is used in production at Twitter (and many other organizations), and is being actively developed and maintained. Finagle is an extensible RPC system for the JVM, used to construct high-concurrency servers. Finagle implements uniform client and server APIs for several protocols, and is designed for high performance and concurrency. Most of Finagle’s code is protocol agnostic, simplifying the implementation of new protocols.

Finatra

Finatra is a sinatra-inspired agile web framework for scala, it runs on top of Finagle.

Ambrose

Twitter Ambrose is a platform for visualization and real-time monitoring of MapReduce data workflows. It presents a global view of all the map-reduce jobs derived from your workflow after planning and optimization. As jobs are submitted for execution on your Hadoop cluster, Ambrose updates its visualization to reflect the latest job status, polled from your process.

Parquest

Parquet is a columnar storage format that supports nested data. Parquet metadata is encoded using Apache Thrift. Twitter created Parquet to make the advantages of compressed, efficient columnar data representation available to any project in the Hadoop ecosystem.

Summingbird

Summingbird is a library that lets you write MapReduce programs that look like native Scala or Java collection transformations and execute them on a number of well-known distributed MapReduce platforms, including Storm and Scalding.

Bootstrap

Bootstrap is a well-known web UI framework used by thousands of companies today. It is a sleek, intuitive and powerful mobile first front-end framework for faster and easier web development.

Bower

Bower is a package manager for the web originally created at Twitter and adopted by a large community. It offers a generic, un-opinionated solution to the problem of front-end package management. It exposes the package dependency model via an API, that can be consumed by a more opinionated build stack. Bower runs over Git and is package-agnostic. A packaged component can be made up of any type of asset and use any type of transport.

Flight

Flight is a lightweight, component-based, event-driven JavaScript framework that maps behavior to DOM nodes. It was created at Twitter, and is used by the Twitter.com and TweetDeck web applications.

Typeahead

Inspired by twitter’s autocomplete search functionality, typeahead.js is a flexible JavaScript library that provides a strong foundation for building robust typeaheads.

Twemcache

Twemcache  is the Twitter Memcached. Twemcache is based on a fork of Memcached v1.4.4 that has been heavily modified to make to suitable for the large scale production environment at Twitter.

FlockDB

FlockDB is a distributed graph database for storing adjacency lists. FlockDB is much simpler than other graph databases such as neo4j because it tries to solve fewer problems. It scales horizontally and is designed for on-line, low-latency, high throughput environments such as websites. Twitter uses FlockDB to store social graphs (who follows whom, who blocks whom) and secondary indices. As of April 2010, the Twitter FlockDB cluster stores 13+ billion edges and sustains peak traffic of 20k writes/second and 100k reads/second
