Hi,

Short introduction; I'm working on making the native JDK 1.3.1 a bit more
stable on -STABLE (4.4 and 4.6.2-SMP in my case) and also trying to backport
Bill Huey's excellent work on Hotspot.

My current test applications are JBoss and Orion (because I want to run
those in production on FreeBSD).

Orion already flies, here are some very simple test results:

 Dynamic Content

  % ab -n 2500 -c 25 http://localhost:8080/examples/jsp/dates/date.jsp


  FreeBSD Native with compiler1:

   Requests per second:    205.64 [#/sec] (mean)
   Time per request:       121.569 [ms] (mean)
   Time per request:       4.863 [ms] (mean, across all concurrent requests)
   Transfer rate:          259.61 [Kbytes/sec] received

  Linux Compatibility with compiler1:

   Requests per second:    1329.07 [#/sec] (mean)
   RTime per request:       18.810 [ms] (mean)
   RTime per request:       0.752 [ms] (mean, across all concurrent requests)
   RTransfer rate:          1677.82 [Kbytes/sec] received

 Static Content

  % ab -n 2500 -c 25 http://localhost:8080/examples/jsp/dates/date.jsp

  FreeBSD Native with compiler1:

    Requests per second:    1119.76 [#/sec] (mean)
    Time per request:       22.326 [ms] (mean)
    Time per request:       0.893 [ms] (mean, across all concurrent requests)
    Transfer rate:          2501.53 [Kbytes/sec] received

  Linux Compatibility with compiler1:

   Requests per second:    1682.41 [#/sec] (mean)
   Time per request:       14.860 [ms] (mean)
   Time per request:       0.594 [ms] (mean, across all concurrent requests)
   Transfer rate:          3758.50 [Kbytes/sec] received

The difference in JSP performance is odd, I'm looking into that now. Could
this be because the version in the linuxulator is more efficient because of
its threading implementation?

There also seems to be a problem with compilation of JSP files. It only
works when I use jikes instead of javac.

Tough stuff, but I'm slowly making progress.


Greetings,

 Stefan
