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 has been added to increase the performance of all Java Runtimes, this is expected to result in significant cost savings from less memory and CPU usage.
