 Zooko posted ["back of the envelope" performance constraints](https://tahoe-lafs.org/pipermail/tahoe-dev/2011-February/006133.html). Bottom-line: you get 30 million ARM instructions to implement one complete digital signature verification.

 Brian and David-Sarah wrote [a simulator]source:trunk/misc/simulators/hashbasedsig.py or two to explore performance trade-offs in (stateless) hash-based signature parameters. The output of one run with the following parameters is this (note that the signing times include regeneration of per-message signing keys from a small long-term private key):
