Hi,
under address http://community.jboss.org/docs/DOC-16676 http://community.jboss.org/wiki/XACMLRBACLocator there is an examle of using many policy sets using configuration xml file.
Is it possible to use many policy sets and load them from the code? e.g.
When I write:
XACMLPolicy ps1 = PolicyFactory.createPolicySet(new FileInputStream(new File("policySet1.xml")));
XACMLPolicy ps2 = PolicyFactory.createPolicy(new FileInputStream(new File("policySet2.xml")));
policies = new HashSet<XACMLPolicy>();
policies.add(ps1);
policies.add(ps2);

How fast does AS 7 start on your computer? This page is a crowdsourced benchmark to see what type of times people are getting. It could also give you an idea if it's time to upgrade your computer to more cores.
Start-up times may vary sligtly between different runs, due to system load, filesystem caching etc. We are interested in your best times :)
On with the showdown! Start JBoss AS 7 in standalone mode and add your results to this page. We are mostly interested in *stock JVM settings*, just to even the playing field. If you add flags, please note that in the JVM column.

h3. JVM flag legend (for table above)
* *Group A*: -Xms64m -Xmx512m -XX:MaxPermSize=256m -client -Xverify:none -XX:+UseFastAccessorMethods -XX:+DisableExplicitGC -XX:+UseCompressedOops
* *Group B*: -server -Xms128m -Xmx128m -XX:MaxPermSize=128m -Djava.net.preferIPv4Stack=true -XX:+UseFastAccessorMethods -XX:+TieredCompilation -Xverify:none
h3. Optimizations
You get better startup times with 32 bit over 64 bit, because of the smaller integer size. If you are on a 64 bit machine, you can do one of two things to get 32 bit performance:
* Run in 32 bit mode using the JVM flag: -d32 (Mac and Windows)
* Use the JVM compression flag: -XX:+UseCompressedOops (option not valid on a 32 bit JVM)
There are also some other JVM flags that will speed things up:
* -noverify
* -XX:+DisableExplicitGC
* -client (32 bit JVM only. You have to edit standalone.sh to use -client instead of -server)
You can squeeze out a few fractions of a second by disabling the console logging (or directing it to /dev/null):
./standalone.sh > /dev/null
You can still view the log output by tailing the server log.
See comments for other suggestions.
Let the best machine win!

How fast does AS 7 start on your computer? This page is a crowdsourced benchmark to see what type of times people are getting. It could also give you an idea if it's time to upgrade your computer to more cores.
When you start the server the first time, it starts slower than subsequent starts. We are interested in your best times :)
During the first startup, AS 7 builds caches and indexes and performs precompilations, "getting to know" your installation and libraries. Filesystem cache also boost performance on subsequent boots (quite noticably).
On with the showdown! Start JBoss AS 7 in standalone mode and add your results to this page. We are most interested in *stock JVM settings*, just to even the playing field. If you add flags, please note that in the JVM column.

h3. Optimizations
You get better startup times with 32 bit over 64 bit, because of the smaller integer size. If you are on a 64 bit machine, you can do one of two things to get 32 bit performance:
* Run in 32 bit mode using the JVM flag: -d32 (Mac and Windows)
* Use the JVM compression flag: -XX:+UseCompressedOops (option not valid on a 32 bit JVM)
There are also some other JVM flags that will speed things up:
* -noverify
* -XX:+DisableExplicitGC
* -client (32 bit JVM only. You have to edit standalone.sh to use -client instead of -server)
You can squeeze out a few fractions of a second by disabling the console logging (or directing it to /dev/null):
./standalone.sh > /dev/null
You can still view the log output by tailing the server log.

[JBoss AS7 Development] - AS 7 startup time showdown
by Takayoshi Kimura
Takayoshi Kimura [http://community.jboss.org/people/tkimura] modified the document:
"AS 7 startup time showdown"
To view the document, visit: http://community.jboss.org/docs/DOC-16971

How fast does AS 7 start on your computer? This page is a crowdsourced benchmark to see what type of times people are getting. It could also give you an idea if it's time to upgrade your computer to more cores.
When you start the server the first time, it starts slower than subsequent starts. We are interested in your best times :)
During the first startup, AS 7 builds caches and indexes and performs precompilations, "getting to know" your installation and libraries. Filesystem cache also boost performance on subsequent boots (quite noticably).
On with the showdown! Start JBoss AS 7 in standalone mode and add your results to this page. We are most interested in *stock JVM settings*, just to even the playing field. If you add flags, please note that in the JVM column.
