There is indeed a small misunderstanding here. I never implied that your advice is inappropriate, it will do the job amply, as I said. And those with a HUGE (or just large) disk, as you say, may probably derive a small additional gain by following it. However, my alternative advice is for those with more moderately sized disks who may prefer a more conservative allocation, as I said, which will probably still allocate an increased space to pagefile thus improving performance. After all, it uses the size recommended by the system itself as initial minimum. This is usually 1.5 x RAM. An eventual pagefile defragmentation, which is only very rarely required anyway, will occur even more rarely, if ever. I also tried to address a small ambiguity in your instructions because some laymen users might not know what value to use here: By the way, there’s more advice for optimizing the pagefile: Move the Pagefile off the system disk to another fast HD, but leave a small amount on C, format the pagefile partition with NTFS, etc, but could confuse users even more. In conclusion, both methods work and the matter is not sufficiently important to merit long argumentation. A user can do what he likes and I leave it up to him.
