slackbuild question
Sorry if this has been answered before, but I couldn't find my answer using the search feature. Anyway, here it goes...I'm build a few packages using a provided slackbuild script. I have changed a few things in the script to optimize the package. Here is my question, in the O2 flag section, should I leave it as O2 or O3? What is the difference between the both of them? Thanks for the replies!!

I suggest O2. Here's a good discussion about it:
"CFLAGS"
"The choice: Summarised
-O2 smaller binary, faster to load from disk, less RAM usage, better cache usage in systems with moderate cpu cache, higher reliability;
-O3 slight to moderate speed increase for some applications, higher memory (RAM, cache and disk) usage, longer load times from disk, very occasional problems with compilation; expect less than 1% improvement in *overall* execution speed."

and
"Options That Control Optimization"
