I've copied -O4 option from dcraw page (http://cybercom.net/~dcoffin/dcraw/) Anyway, just tested it on FreeBSD7/i386 on Intel C2D Execution time for LibRaw test is near same for -O3 and -O4 There is significant difference between -O2 and -O3 (about 10%) So, you can change to -O3 in port Makefile patches I will also change to -O3 in future LibRaw releases. -- Alex Tutubalin Web: http://blog.lexa.ru mailto:lexa@lexa.ru
