Hi Alejandro, > The strange thing is that when looking at options enabled at different -O levels (trying to remove the ones that were using more memory), ended up with a GCC 4.2.3 command-line that specified exactly all the options enabled by -O2 (as listed in the manpage), and built. But ran at the same speed as without them. Which -O# level were you using in conjunction with the specified -f? Keep in mind, that at -O0, all optimizations are disabled, and the -f to enable a particular optimization have no effect since all optimizations are disabled. Sincerely, --Eljay
