You know, to be honest I never really cared about what the values meant, but
more about the percentage, and I probably should have showed the other
numbers to get a full picture. Anyhow I found some info on what those
values are I'll paste here:
"In time-based profiling, the application to be analyzed is run at full
speed on the same machine that is running AMD CodeAnalyst. Time-based
samples (collected at predetermined intervals) can be used to identify
possible bottlenecks, execution penalties, or optimization opportunities.
The numbers are called timer samples. It is not often that I get
opportunities to optimize code, but I can say that I've had success with
this tool in the past. One of the greatest moments it helped me was when I
was writing a reverb effect, and it identified the bottleneck being one line
of code (normalize), when I optimized that line it took a dramatic effect of
using 40% cpu to 2!
