There is no faster way to sync the blockchain. Do not use the bootstrap.dat file, it is old, out of date, and will be slower. Just let it sync normally, that's all you can do.

"At the beginning" blocks are small, so you should quickly go through the first few "years behind", even though the directory size doesn't go up much. So this seems normal.
Later on, I've noticed (and tested) the speed is mainly limited by my harddrive. If you can, use a SSD (if you're not already doing it). When I tested this from a ram-drive, my CPU become the limitation, while running from my laptop's hdd the CPU was mainly idle waiting for the disk.

I have a SSD

I understand. I will wait
