GlassFish v2, the Fastest Application Server on the Planet

Based on the recently published benchmark, GlassFish V2 now has the best (883.66 JOPS@Standard) SPEC jAppServer 2004 score on Sun Fire T2000. Read this blog for details. On the same comparable hardware, GlassFish V2 is #1! Here are the relevant SPEC jAppServer 2004 scores...

I think the reason is "JDK6 out perform JDK5", not the app server itself.

Latest GlassFish V2 result is almost 70% higher than previous score of 521.42 JOPS@Standard on a Sun Fire T2000 (was running at 1.2ghz). GF V2 is not 70% faster than GF V1, but it is quite substantially faster. I am very pleased to see the highest ever score on the Sun Fire T2000 with GlassFish V2.

Also, see this thread on TSS about this topic and the usage of JDK 6.

Here is Scot's comment: If you want JDK6, you have to use glassfish
Henrik makes a good point that JDK 6 contributes to our performance (though probably not as much as he assumes). Which is yet another reason why Glassfish is the superior appserver: we've supported JDK 6 for more than 6 months. Weblogic doesn't support it today, and as far as I've heard they have no plans on supporting it for months to come. So it's not apples-to-apples, but then again, neither is the marketplace.

I am glad to see that Java SE (JDK) team at Sun also worked on performace. Great!

While I don't actually doubt that GlassfishV2 is fast, the testing may be flawed. I see in there that a Sun SPARC Enterprise T2000 was used while the others were Sun Fire T2000. Then there's the Java version like the first poster mentions. The fact that the hardware is roughly the same is only a part of the equation. The operating system, the amount of memory, and the pipe between the database and the application server all make huge differences.

I clicked through to a couple of the linked results pages and you can see that there are a ton of differences between the deployments. The tests involved different database technologies and different JDBC drivers. So the tests are less comparative than they need to be.

I think the only thing really proven is that Glassfish can give all the other application servers a run for their money in real world deployments. To me that statement means I keep an eye on Glassfish and wait for some truly solid benchmarks in homogeneous system setups, especially Windows server setups with SQL Server databases.

Hi Chris:

Thanks for expressing your interest in GlassFish.

Both Sun SPARC Enterprise T2000 and Sun Fire T2000 use the same UltraSPARC T1 processor. Refer to:

SPEC jAppServer 2004 is a industry standard benchmark that all vendors use to publish the results. AFAIK, this is a leading benchmark in this area.

GlassFish is faster than IIS 7.0 + C# but slower than Apache + PHP, and much slower than G-WAN and its ANSI C scripts:

And when comparing Web servers:

Requests per sec. .. Server .................. Type of Server
142,000 ............ G-WAN ................... (a Web Application server)
80,000 ............ Nginx ................... (a Web server)
60,000 ............ Lighttpd ................ (a Web server)
52,000 ............ Apache Traffic Server ... (Yahoo!'s "Web accelerator")
28,000 ............ Varnish ................. (Facebook's "Web accelerator")

G-WAN is again the fastest.
