Last time it was tried, LTO regressed performance compared to the PGO builds we produce (and yes, both LTO and LTO+PGO were tried). We recently upgraded GCC to 4.8, so we can give it another spin, but I don't think 4.8 would make a significant difference here. I want to update to 5.3 next cycle (but keeping the minimum supported version at 4.8), maybe that one would make a difference.
