[Insight-users] MacOS 10.2 speed issues

[Damion Michael Shelton]

Hi everyone, it was suggested on the tcon that this info might be of
general interest...

When compiling an ITK-based application on OS 10.2, there is a dramatic
speed difference between -O2 and -O3 optimization. With our app, execution
time decreased from a little over 4 minutes to approximately 10 seconds
when moving from -O2 to -O3. -O3 takes significantly more time to build,
but the execution time decrease makes this worthwhile.
