The PostgreSQL read performance takes a noticeable hit to the performance with KPTI, but hopefully you are not running any Linux i686 servers in production still...

Workloads like The GIMP with image manipulation also take a noticeable hit to performance.

Redis is another server component that does take a noticeable hit to performance with KPTI enabled, but hopefully all of your 32-bit Linux servers have since been retired.
