Apache Traffic Server v3.0.0 Features-At-A-Glance
In the works over the past year (v2.0 was released May 2010), Apache Traffic Server v3.0.0 is the result of contributions from more than 30 developers and contributors. Technical highlights include:
- Over 1,000 "commits" (code, patches, or documentation written directly to the code repository);
- 380+ bug tickets resolved;
- 10 releases have been made during the development phase (v2.1.0 - 2.1.9)
II. New features/improvements
- Full 64-bit support;
- Client side IPv6 support;
- WCCP (Web Cache Communication Protocol);
- Clustering is functional and supported (many benefits include an efficient distributed cache);
- Major plug-in API improvements, making the APIs more feature rich and easier to use;
- Support for many platforms, including OSX, Solaris and FreeBSD (Linux, of course, was always supported);
- New improved RAM cache algorithms, for better performance and memory utilization
- Many configurations are now configurable per transaction (or per mapping rule)
- Many improvements in statistics and management APIs;
- Multiple accept threads, and a dedicated DNS thread:
- Build environment is now much more flexible, and package owner friendly;
- Many, many bug fixes for improved stability and functionality.
III. Performance improvements
- Overall throughput is 2-3x improved over v2.0 (depending on the traffic patterns)
- Response latency is up to 5x better than v2.0
- Benchmark: Serving small objects out of RAM cache, a high end server has showed over 220,000 requests / second
- Benchmark: Serving small objects that are not cacheable, the same high end server could proxy 100,000 requests / second
(NOTE: all benchmarks are on local network, with keep-alive)

The Apache Software Foundation Announces Apache Traffic Server v3.0.0
Highly-Performant Cloud Computing Service Serves Dynamic Content, Billions of Objects, and Terrabytes of Data for Large-Scale Deployments
14 June 2011 —FOREST HILL, MD—The Apache Software Foundation (ASF), the all-volunteer developers, stewards, and incubators of nearly 150 Open Source projects and initiatives, today announced Apache Traffic Server v3.0.0.
"Traffic Server is battle hardened, serving terrabytes of data in real-life deployments where immediate content delivery is critical," said Apache Traffic Server Vice President Leif Hedstrom. "V3.0.0 builds upon that foundation, with new features and functionality, improved efficiency and performance, increased uptime, and overall easier to use.”
Apache Traffic Server is a fast, scalable, and extensible HTTP/1.1 compliant caching proxy server designed to improve:
- Caching: improves response time while reducing server load and bandwidth needs by caching and reusing frequently-requested Web pages, images, and Web service calls;
- Proxying: easily add keep-alive, filter or anonymize content requests, or add load balancing by adding a proxy layer;
- Speed: scales well on modern SMP hardware, handling tens of thousands of requests per second;
- Extensibility: APIs allow for customized plug-ins, from modifying headers and content to implementing new protocol handlers;
- Reliability: successfully handles hundreds of terrabytes of data, both as forward and reverse proxies
Apache Traffic Server v.3.0.0 has been benchmarked to handle more than of 200,000 requests per second -- a 277% improvement over v2.0’s already-impressive rates. Used in production in a variety of large-scale deployments, companies such as Yahoo! rely on Apache Traffic Server to handle over 400 terrabytes of traffic, and has used the project to serve more than 30 billion objects daily across its various properties including the Yahoo! homepage, and its Sports, Mail, and Finance sites.
Apache Traffic Server entered the Apache Incubator in June 2009, graduated as an Apache Top-Level Project (TLP) in April 2010, and released v2.0 the following month. For technical highlights, please refer to the Apache Traffic Server v3.0.0 Features At-A-Glance at http://s.apache.org/7Or
Availability and Oversight
As with all Apache products, Apache Traffic Server software is released under the Apache License v2.0, and is overseen by a self-selected team of active contributors to the project. A Project Management Committee (PMC) guides the Project’s day-to-day operations, including community development and product releases.
