Well, I was not expecting to produce a report after throwing that
comment, but given it's my fault ;)

We have a bunch of production servers that do a lot of SSL work, mostly
handling HTTPS connections. When we started having troubles with slow
establishing connections, we looked into the entropy level available in
the servers, and in many occassions entropy was depleted. We bought two
keys for testing, deploy them, and the entropy was there up to 4Kb most
of the time. We never saw the slowdowns again. Before deployment, we did
some testing and although there was no conclusive results in terms of
speed, there was some benefit on the number of HTTPS sessions the server
was able to handle.


I hope it helps!

PS: We don't use the Entropy Keys in our DNSSEC deployment, keys are
created within the HSM, which provides high-quality RNG
