Make Premiere faster to export

Question

I'm not sure that this has been asked in a while, so here goes:

Why is Premiere so reluctant to use my available CPU/GPU power? I am currently waiting while a 1920x1080 25fps 2m 30s sequence exports. It has a few effects - nothing complex (a track matte and a colour grade) but PPro is being pathetically slow, taking something like 15 minutes to do the export (to H.264). Premiere is using only ~15% of my CPU and just ~10% of my GPU. Why?! Is the app just really inefficiently coded? Has Adobe done absolutely nothing to take advantage of those newfangled multi-core processors that were introduced a couple of ~~weeks~~ decades ago? Are there any plans to radically overhaul whatever is causing this frustrating reluctance to use the available power?

Not every process is limited by CPU/GPU power. Some are limited by available RAM; some are limited by storage access speed.

Also, many processes cannot be GPU-accelerated; the introduction of one non-GPU-acclerated effect on a track item, can force all effects on that track item to not be accelerated.

>Has Adobe done absolutely nothing...

If you read PPro's release notes, you will see that we've been actively/vigorously accelerated slower parts of the application, for years.
