In response to the recent discussion of push v pull Ajax performance, I decided to do some performance testing of the Jetty implementation of bayeux for the cometd project. This was also a great way to test the asynchronous http client that is now included with Jetty. The test scenarios Read more…
A recently blogged about my thoughts on the JSR-315 Asynchronous servlet 3.0 concerns. I have now worked those thoughts into a proposal that I have submitted to the expert group. This proposal is clearly influenced by Jetty Continuations in that it allows requests handling to be suspended and resumed. However Read more…

The Ajaxian has covered a study of push vs pull Ajax communication techniques. The original report was produced by Delft University. I welcome this report as a good start on objectively measuring the communication techniques needed for web 2.0 applications, but unfortunately the report contains a couple of minor misconceptions Read more…
The Java Community Process has proposed JSR-315 to consider the 3.0 servlet specification. In this blog entry, I look at the Async and Comet considerations listed in the JSR-315 and discuss how 3.0 servlets might address them. From JSR-315 – Async and Comet support: Non-blocking input – The ability to Read more…
I’m just fresh out of a session at JavaOne where Sun have revealed their road map for the servlet 3.0 specification. My initial reaction is that it contains both some good and bad items as well as quite a few concerns in between. The 10 words or less version is: Read more…
Terracotta is an infrastructure that allows you to pretty much transparently cluster any code in a jvm. We’ve already successfully used it to cluster the channels in Jetty’s Bayeux (aka Cometd) implementation, so we thought it was high time we used it to cluster HTTP sessions. Jetty already has a Read more…
