Hi, Spankar,
You really take me a bad news, you know, actually what
I want to find is a good JIT for my servlet run on linux.
:-(
I am hardly able to image the thing is so bad. Even
though I myself have never(don't laugh me) met any
problems with Symantec JIT on windows, I'd rather
believe you.
So, I have to wait for hotspot or some stable JIT.
According with the sun's schedule, they should give
a beta version of HotSpot maybe in June. Do you know
(or dose somebody know) who(blackdown?) will port this
product to linux? Or who could give some comments on
the performance of some well-known servlet engine(JRun,
JServ, ....)
Thanks again, Sankar.
