Yes. There were some stones left unturned in the cold startup area.
Turns out that every single large application suffers from low io
throughput likely due to lack of cooperation between the dynamic linker
and the kernel.
There is a glibc bug filed on that.

Unfortunately, few userspace people seem to know exactly how madvise()
hints behave, so I was hoping someone on LKML would clue me in.
