Hi Yury, Not sure if this was already covered in this thread, but with N smaller cores on a single N-CPU-core box you could run N queries in parallel over smaller indices, which may be faster than a single query going against a single big index, depending on how many concurrent query requests the box is handling (i.e. how busy or idle the CPU cores are).
