Big CPU and slow disk...
You should add another disk just for the WAL -- disks are pretty cheap
these days.
Writing the WAL on a second disk is the first thing to do on a
configuration like yours, if you are limited by writes.
It also reduces the fsync lag a lot since the disk is only doing WAL.
Good idea -- where can I set the path to WAL?
At install, or use a symlink (they exist on windows too !...)

I've no idea of the other needed NTFS tweaks, like if there is a
noatime/nodiratime ?...
