Syncing --no-warp is slow even with Optane #11671

Hi everyone!

I've recently started syncing another ethereum node, and I've noticed that my server is running on 20% CPU, almost no RAM, and it's sycning at 9 blocks a second. We're only on 1.7Mil blocks We are even using Intel Optane storage

No disk IO, almost no RAM consumed, 20% CPU, 82 peers.. why is this happening?

Found the issue - syncing with parity-2.7.2 slows down at around 2,340,000 blocks.

Find out why here.

Quick fix would be to downgrade to parity-2.5.13 and re-sync
