I concur. Ldd reports that neither gcc nor g++ link libpthread (the only multithread library I have installed) which would indicate they are single-thread compilers and as such can fit themselves on one core in multi-core setups. The other core(s) can take over other tasks, a capability single core CPUs don't have. So, on single core CPUs, any additional tasks would affect GCC execution times, while on multi core CPUs, this would not occur. -- -Aleksandar Kuktin -- http://linuxfromscratch.org/mailman/listinfo/blfs-dev FAQ: http://www.linuxfromscratch.org/blfs/faq.html Unsubscribe: See the above information page
