Over the past few years, Webtide has been working closely with Google to improve the usage of Jetty in the App Engine Java Standard Runtime. We have updated the GAE Java21 Runtime to use Jetty 12 with support for both EE8 and EE10 environments. In addition, a new HttpConnector mode Read more…
Java’s Virtual Threads (aka Project Loom or JEP 444) have arrived as a full platform feature in Java 21, which has generated considerable interest and many projects (including Eclipse Jetty) are adding support. I have previously been somewhat skeptical about how significant any advantages Virtual Threads actually have over Platform Read more…
TL;DR This is a quick blog to share the performance figures of Jetty 12 and to compare them to Jetty 11, updated for the release of 12.0.2. The outcome of our benchmarks is that Jetty 12 with EE10 Servlet-6.0 is 5% percent faster than Jetty 11 EE9 Servlet-5.0. The Jetty-12 Read more…
One can only improve what can be reliably measured. To assert that Jetty’s performance is as good as it can be, doesn’t degrade over time and to facilitate future optimization work, we need to be able to reliably measure its performance. The primary goal The Jetty project wanted an automated Read more…
The Jetty Project just released the Jetty Load Generator, a Java 11+ library to load-test any HTTP server, that supports both HTTP/1.1 and HTTP/2. The project was born in 2016, with specific requirements. At the time, very few load-test tools had support for HTTP/2, but Jetty’s HttpClient did. Furthermore, few Read more…
“Project Loom aims to drastically reduce the effort of writing, maintaining, and observing high-throughput concurrent applications that make the best use of available hardware. … The problem is that the thread, the software unit of concurrency, cannot match the scale of the application domain’s natural units of concurrency — a Read more…
Since Loom is now available in OpenJDK 16 early access includes, we thought it was a good time to test out some of the amazing claims that have been made for Duke’s new opaque clothing that has been woven by Loom! Spoiler – Duke might not be naked, but its attire could be a tad see-through!
Context The Jetty HTTP client internally uses a connection pool to recycle HTTP connections, as they are expensive to create and dispose of. This is a well-known pattern that has proved to work well. While this pattern brings great benefits, it’s not without its shortcomings. If the Jetty client is Read more…
Jetty 9 introduced the Eat-What-You-Kill[n]The EatWhatYouKill strategy is named after a hunting proverb in the sense that one should only kill to eat. The use of this phrase is not an endorsement of hunting nor killing of wildlife for food or sport.[/n] execution strategy to apply mechanically sympathetic techniques to the Read more…
Jetty’s venerable MultiPartInputStreamParser for parsing MultiPart form-data has been deprecated and replaced by the much more efficient MultiPartFormInputStream, based on a new MultiPartParser. This is much faster, but less forgiving of non-compliant format. So we have implemented a legacy mode to access the old parser, but with enhancements to make Read more…
