I have been working lately with the new JDK 7’s Async I/O APIs (“AIO” from here), and I would like to summarize here my findings, for future reference (mostly my own). My understanding is that the design of the AIO
Jetty 9.1 in Techempower benchmarks
Jetty 9.1.0 has entered round 8 of the Techempower’s Web Framework Benchmarks. These benchmarks are a comparison of over 80 framework & server stacks in a variety of load tests. I’m the first one to complain about unrealistic benchmarks when
Jetty-9 goes fast with Mechanical Sympathy
Since we discovered how to make Jetty-9 avoid parallel slowdown, we’ve been continuing to work with micro benchmarks and consideration of Mechanical Sympathy to further optimise Jetty-9. As we now about to go to release candidate for Jetty-9, I thought
Avoiding Parallel Slowdown in Jetty-9 with CPU Cache analysis.
How can the sum of fast parts be slower than the sum of slower parts? This is one of the conundrums we faced as we have been benchmarking the latest Jetty-9 releases. The explanation is good insight into modern CPUs
The new Jetty 9 HTTP client
Introduction One of the big refactorings in Jetty 9 is the complete rewrite of the HTTP client. The reasons behind the rewrite are many: We wrote the codebase several years ago; while we have actively maintained, it was starting to
Jetty, SPDY and HAProxy
The SPDY protocol will be the next web revolution. The HTTP-bis working group has been rechartered to use SPDY as the basis for HTTP 2.0, so network and server vendors are starting to update their offerings to include SPDY support.
Why detecting concurrent issues can be difficult
Jetty 9’s NIO code is a nearly complete rewrite with improved architecture, cleaner and clearer code base and best of all it’ll be even faster and more efficient than jetty 7/8’s NIO layer. Detecting concurrent code issues is usually not
SPDY Push Demo from JavaOne 2012
Simone Bordet and I spoke at JavaOne this year about the evolution of web protocol and how HTTP is being replaced by WebSocket (for new semantics) and by SPDY (for better efficiency). The demonstration of SPDY Push is particularly good
Jetty 9 – Updated WebSocket API
Creating WebSockets in Jetty is even easier with Jetty 9! While the networking gurus in Jetty have been working on the awesome improvements to the I/O layers in core Jetty 9, the WebSocket fanatics in the community have been working
Jetty 9 – Features
Jetty 9 milestone 0 has landed! We are very excited about getting this release of jetty out and into the hands of everyone. A lot of work as gone into reworking fundamentals and this is going to be the best
