No real obvious single-instruction hotspots i can see.
But i can see another problem: the function is too large and its flow
is not fall-through in any way. As you can see it from the profile
distribution it is broken into 25-30 separate code sequences.
The function consists of more than 1200 instructions and is 5200 bytes
large. According to the profile above, only 350 instructions are used
and about 850 of those instructions are never used by this workload.
So in theory this function should only take up ~1.5K of the
instruction cache.
But because execution is spread out into 25+ smaller pieces, it takes
up ~4K of the instruction cache instead (there's a single ~1.2K hole
in the middle, i subtracted that) - 2-3 times larger than it should.
So this code could make good use of the (brand-new ;-) branch-tracer
ftrace plugin and grow a few well-placed likely()/unlikely() places -
at least for this workload. I think.
