Subject Re: [launcher] Patch is available for "harmonyvm.properties" parsing
Date Sat, 23 Sep 2006 11:42:49 GMT
You are right. It is different property file:
   $JRE/lib/boot/bootclasspath.properties  (6kbyte)

The strace looks like following. Not quite effective.
The number of syscalls is greater then all others at the startup of
VM. I would like to file a performance JIRA for the issue, but I don't
quite understand if it DRLVM specific or classlib?
