Leo, I've just tried and could not reproduce DRLVM failure (svn = r470676, (Nov 3 2006), Linux/ia32/gcc 3.3.3, debug build, SUSE9). I have only JRockit installed and got the following timings:
BEA JRockit 1.5.0 4.6/4.6 Harmony j9 1.4/1.4 Harmony DRLVM (debug) 6.5/6.5 2006/11/3, Leo Li <[EMAIL PROTECTED]>:
They are the total test run times and I really feel that harmony launches slower than RI. It is the most abvious difference not only from the above result. I have once tested the performance about net and the result ensures me that harmony performances almost as good as RI although the test I run cannot be said a formal performance test.:) On 11/3/06, Alexey Varlamov <[EMAIL PROTECTED]> wrote: > > 2006/11/3, Alexey Petrenko <[EMAIL PROTECTED]>: > > More and more good new from day to day :) > > > > Thanks, Leo! > > > > SY, Alexey > > > > 2006/11/3, Leo Li <[EMAIL PROTECTED]>: > > > Hi, all > > > I have just tested JUnit4.1 on Harmony. > > > With J9 VM, harmony passes both on windows xp2 and redhat > enterprise > > > 4.0.
