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. http://sourceware.org/bugzilla/show_bug.cgi?id=11431 Unfortunately, few userspace people seem to know exactly how madvise() hints behave, so I was hoping someone on LKML would clue me in.
