To put it mildly, OpenSolaris 2009.06 didn't just beat Ubuntu 9.04 in the Java
2D Microbenchmark test, this was total annihilation!!! 2009.06 performed at
least twenty times better than Ubuntu 9.04 did in the Java 2D Microbenchmark
v1.0 Vector Graphics competition. This was very surprising for me to read as
I'm used to Ubuntu doing much better than OpenSolaris in all of these phoronix
test suite articles (I always chalked it up to the test suites being compiled
with a newer version of gcc on Ubuntu and to gcc compiler being optimized for
GNU/Linux in the same way that I assume Sun Studio is optimized for Solaris).
A lot of the CPU intensive tests depend more on being compiled for amd64
mode by default on Ubuntu than the gcc version. gcc 3.4.3 with -m64 was
competitive, if not better, than Ubuntu.
OpenGL graphics performance on NVIDIA can depend on Solaris running in
thread
safe mode all the time, even for a single threaded application. Thread
unsafe
mode is the default on Ubuntu when not compiling for threads. Again,
when thread safe mode is disabled on OpenSolaris the OpenGL benchmarks
are competitive, if not better, than Ubuntu.
