Here are my conclusions: Although these results don't explain the
whole story, the XP/Intel Chandler launch advantage of 3.5 seems like
it could be entirely be explained by the difference in C performance.
Furthermore, a significant part of this advantage is due to the
Microsoft compiler. There are more tests that would be interesting to
do: profile the C code in Chandler to see where time is spent during
launch and other time consuming tasks. Run tests on the Intel Macs.
Measure how much IO is involved running Chandler. Construct some
Berkeley DB benchmarks and measure them on the different platforms.
Finally, Given Moore's law, the current state of Chandler, and its
probable lifetime (assuming it's successful), performance probably
won't be a significant obstacle to adoption.
Is it worthwhile trying to compile some of the smaller benchmarks on
Windows using gcc to get some idea of how bad off we are using GCC?
We could do release builds on the mac using either the IBM XLC compiler
or on Mac OS intel using intel's compiler
