The following post is a comprehensive summary of the developer-facing changes coming in Java 8. At the time of this writing, Java 8 development is still very much in progress. It had the best support for the Java 8 language features at the time I went looking. Language features and APIs may still change. Interface improvements.
We’re pleased to announce Round 22 of the TechEmpower Framework Benchmarks! The TechEmpower Framework Benchmarks project celebrates its 10th anniversary, boasting significant engagement with over 7,000 stars on GitHub and more than 7,100 Pull Requests. Follow us on Twitter for regular updates.
Netty , Vert.x , and Java servlets are fast, but we were surprised how much faster they are than Ruby , Django , and friends. In third place is plain Java Servlets running on Cauchos Resin Servlet container. For example, on the Java platform, Jackson was used for frameworks that do not provide a serializer. Java / JVM.
But check out what they can do: techempower@lg01:~$ wrk -d 30 -c 256 -t 40 [link]. Undertow is the lightweight Java web application server used in WildFly. Loaded up with disks, these servers are around $8,000 a piece direct from Dell. Running 30s test @ [link]. Transfer/sec: 130.83MB. It just happens to be quite quick at HTTP.
Now in its fifth year, the TechEmpower Framework Benchmarks project has another official round of results available. See [link] pic.twitter.com/Od1nuq0UQV — TechEmpower Framework Benchmarks (@TFBenchmarks) May 17, 2018. As hinted above, we created a Twitter account for the TechEmpower Framework Benchmarks project: @TFBenchmarks.

Let me share a few trends that I've noticed when dealing with streams and stream concatenation in general, having written a fair amount of code in Java 8 by now. There have been maybe one dozen cases where I've needed to concatenate streams.
This round adds Bottle (Python), Dancer (Perl), Kelp (Perl), MicroMVC (PHP), Mojolicious (Perl), Phalcon (PHP), RingoJS (JavaScript), Spark (Java), and Wai (Haskell). As with previous rounds, the developer community has contributed several additional frameworks for Round 4, bringing the total to 57!
Third place is held by plain Java Servlets running on Caucho''s Resin Servlet container. Java / JVM. Repeating its performance from last week, the Netty platform holds a commanding lead for JSON serialization on EC2. Vert.x , which is built on Netty, retains second place. The latency data is captured at 256 concurrency. Web servers.
Round 3 includes Snap on Haskell; Elli and Cowboy on Erlang; Openresty on Lua; Tornado on Python; Onion on C; Slim, Codeigniter, Phreeze, Kohana, Lithium, Laravel, Silex, Fuel, and Symphony2 on PHP; Grizzly-Jersey and Play1 on Java; Scalatra, Lift, Unfiltered, and Finagle on Scala. The full results table is huge.
from Java's standard libraries. Historically, Enum{Set,Map} were recommended as a matter of safety, taking better advantage of Java's type system than the alternatives. Effective Java goes into detail about this use case for Enum{Set,Map} and enum types in general. This article discusses java.util.EnumSet. and java.util.EnumMap.
Theoretically we can send it from a Java server to a JavaScript client via JSON and both sides see exactly the same number. To convince ourselves that this number is safe, we examine various representations of this number in Java and JavaScript: // In Java long x = 1L. It passes our verifyLongFitsInDouble check.
This change was unintentionally done in the Compojure test by TechEmpower staff, and then later copied to http-kit to keep the implementations in sync. All JVM-hosted tests have been upgraded to Java 8. We have corrected this error in Round 12. Other notable changes. The plain PHP, Slim, and Laravel tests have been upgraded to PHP 7.
jawn (java). mangooio (java). Meanwhile, the total number of frameworks has increased by 26. The new frameworks are: silicon (C++). aleph (clojure). pedestal (clojure). crystal-raw (crystal). moonshine (crystal). sails (js). clancats (php). limonade (php). asyncio (python). cherrypy (python). webware (python). klein (python).
Compiled languages such as C, C++, Java, Scala, and Ur continue to dominate most tests, and Lua retains its unique position of standard-bearer for JIT languages by showing up within the top 10 on many test types. About TechEmpower. But we expect the other top contenders won''t leave this a settled matter.
