Today I changed the profiler in ABCL to determine hot spots in our
code, by looking only at the 8 stack frames at the head of the stack.
The outcome of running the test suite with that changed profiler is
10.0 271135 TMS
10.2 275152 TIMESIN
10.7 289952 SIMPTIMES
11.1 300877 GREAT
12.3 332154 KINDP
13.7 371011 MEVAL1
14.1 382393 DMARK
15.8 427010 MEVAL
26.1 706542 SIMPLIFYA
74.3 2009777 DLSF
80.5 2177991 DLS
92.2 2493681 DGRF
100.0 2705263 DGR
Where DGR is the hottest spot and the others are percentages of that.
So, it looks like it that DGR is in the 8 most recent stack frames the
most often of all functions used. Note this is based on sampling at a
rate of 1ms intervals, not exact measurement.
I'm hoping together we can explain the outcomes?
