I'm guessing that trying to get chandler/wx building on a different
compiler is going to be a nightmare - not because of compiler
incompatibilities, but because getting all the Makefiles to do what we
want is going to be extremely tedious.. and its not clear to me if
there is any benefit beyond confirming that in fact VC++ is a better
compiler than gcc.
It seems like what we've determined is "the python benchmarks are
slower on mac than windows because of gcc" - and that this is probably
true for all python apps... but Chandler on Linux isn't that bad.
While I think this was a useful exercise so that we can have a
baseline to compare windows to mac, it doesn't really explain why the
mac is also much faster than Linux. It sounds like we need to start
focusing on chandler-specific stuff, specifically wx and berkeleydb.
I didn't mean compiling all of chandler using gcc, just the micro
benchmarks so that we could see if the perf ratios change with the
compiler on the same platform.
Also my experience is the reverse, namely Linux is much faster than the
Mac. Or is that what you meant? I did some benchmarks on berkeleydb a
while back, and perf on mac was definitely not the same as on the other
platforms.
