Thanks. I'll check out perf later (thanks for the tips!), but for
now, here's the function which was at the top of my oprofile
results, annotated with those options. I'm afraid it's a bit
intimidating to me -- the last time I did much with X86 assembly
language was in the mid-80s, on an 80286. :-/ Hopefully, since
this is at the top of the oprofile results when running with
prepared statements, it will be of use to somebody.
The instructions which are shown as having that 1% still seem odd to
me, but as you say, they were probably actually waiting for some
previous operation to finish:
43329 0.3211 : 70b56a: test %rbp,%rbp
99903 0.7404 : 70b58a: mov %rax,0x18(%rsp)
If anyone wants any other detail from what I captured, let me know.
