默认 【转帖】why Of So Big Differences

why of so big differences?
why of so big differences?
bonjour,
with directdwg 1.14.02, i compiled odcopyex for mac os x with macosx lib and with macxc lib and for macintel with macub lib.
the sizes of tha app. are :
for macintel : 10.6 mb
with macosx : 14 mb ??
with macxc : 16.2 mb ???
the same dwg file converted in dxf :
with macosx lib : 44 sec
with macxc lib : 2 mn 20sec ??? (on the same mac powerbook g4 1.67 ghz)
the same file but on a macintel mini core solo :
compiled for i386 : 23 sec - very good
with macosx lib : 37 sec (ok it is under rosetta)
so why of so big differences?
thanks
eric p.
our macosx libs are built with -o optimization (equivalent to -o1). the xcode libs are built with -os (default for xcode projects). we recently changed our xcode settings to -o0 (no optimization), since -os was causing some problems for us.
we will change the xcode settings to -o1 for the next release, which should give this version performance & size comparable to the macosx libs.
