I have updated Deadwood to optionally use RadioGatún; the default is still to use RadioGatún.
On 64-bit systems, not surprisingly, the 64-bit version of RadioGatún is about 45% faster than the 32-bit version. What did surprise me is that, on 32-bit systems, the 64-bit version is about 5% faster than the 32-bit version. While the 64-bit version needs more operations on a 32-bit CPU, these operations are done only half the time; one gets an overall performance boost.
One advantage the 32-bit version does have is that its code is about 33% smaller (600-700 bytes smaller) than the 64-bit code on 32-bit systems.
RadioGatún, unlike ARX (add-rotate-exclusive or) ciphers, only performs bitwise rotations, exclusive or, and bitwise or operations, so it does not have the performance penalty running the 64-bit version on a 32-bit system that ARX ciphers have.

Using the COCOMO II - Constructive Cost Model and my take-home pay at the time I started developing MaraDNS (which is less than what I actually cost my then-employer), MaraDNS is worth about two million dollars (US currency). I have freely donated all this effort to the Internet for anyone to download and use.
I devoted a decade of my life and $2 million worth of software development time making MaraDNS.
If I do the following in CentOS 6:
xterm -fn 7x14
I get almost no Unicode characters, but if I do this incantation:
xterm -fn -misc-fixed-medium-r-normal--14-130-75-75-c-70-iso10646-1
I get reasonably good Unicode BMP coverage (including smart quotes).
