As Paolo suggested, I have tried to use new based allocator and configure
gcc with --enable-libstdcxx-allocator=new.
Results are:
File 341-O0 350-O0 Delta% 341-O1 350-O1 Delta% 341-O2 350-O2 Delta%
basic_seq.cc 3.78 3.60 5.0 4.01 3.76 6.6 3.92 4.01 -2.2
which looks like --enable-libstdcxx-allocator=new is a good candidate for
a fast C++ compilations. :-) I hope I will be able to test it on a full
orb directory to see all results.
Cheers,
Karel
