Helm is quite fast. I tried it on the Linux kernel, and Helm can display all 46678 files and navigation (like move to next/previous line or <next>/<prior>) is still fast, but not feel as "smooth". If you have anything under 30000 candidates, everything behaves normally. You can try with Projectile using projectile-find-file to list all files. Be sure to set helm-candidate-number-limit to 30000 and set projectile-completion-system to Helm.
