We have SPDY to SPDY and HTTP to SPDY proxy functionality implemented in Jetty for a while now. An important and very common use case however is a SPDY to HTTP proxy. Imagine a network architecture where network components like firewalls need to inspect application layer contents. If those network Read more…
This blog is an update for jetty-9 of one published for Jetty 7 in 2008 as an example web application that uses Jetty asynchronous HTTP client and the asynchronoous servlets 3.0 API, to call an eBay restful web service. The technique combines the Jetty asynchronous HTTP client with the Jetty Read more…
Having discussed the business case for Jetty 9 and SPDY, this blog presents a simple tutorial for runing PHP web applications like WordPress on Jetty with SPDY. Get Jetty First you’ll need a distribution of Jetty, which you can download, unpack and run with the following (I use wget to Read more…
So you are not Google! Your website is only taking a few 10’s or maybe 100’s of requests a second and your current server is handling it without a blip. So you think you don’t need a faster server and it’s only something you need to consider when you have Read more…
The folks at Plumbr have done some interesting data harvesting from the anonymous phone home data provided by the free version of their memory leak detection system. This has allowed them to determine the most popular application servers from their user base. From over a 1000 installations they were able Read more…
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 API aimed at simplifying non-blocking operations, and it does: what Read more…
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 does not do well, so before crowing about our Read more…
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 I’d give a quick report on the excellent results we’ve Read more…
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 and an indication of how software engineers need to be Read more…
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 show its age. The HTTP client guarded internal data structures from Read more…
