Subject: Re: [RFC] frandom - fast random generator module
Date: Thu, 16 Oct 2003 21:28:58 +0200 [thread overview]
Message-ID: <3F8EF17A.2040502@users.sf.net> (raw)
In-Reply-To: <ugzng1axel.fsf@panda.mostang.com>
Allow me to supply a couple facts about frandom:
* It's not a "crappy" RNG. Its RC4 origins and the fact, that it has
passed tests indicate the opposite. A fast RNG doesn't necessarily mean
a bad one. I doubt if any test will tell the difference between frandom
and any other good RNG. You're most welcome to try.
* Frandom is written completely in C. On an i686, gcc compiles the
critical part to 26 assembly instructions per byte, and I doubt if any
hand assembly would help significantly. The algorithms is clean and
simple, and the compiler performs well with it.
