Yes, unfortunatly there is no optimized library aviable for x86
before pentium processors (as they were the first generation to
bundle an arithmetic co-processor).
Anyway, I will help you building a native library if needed.
from
http://www.amd.com/us-en/ConnectivitySolutions/ProductInformation/0,,50_2330_9863_13022%5E13058,00.html,
I don't get what instruction set is supported :
"x86/x87-compatible core" / " Integrated FPU that supports the
Intel MMX? and AMD 3DNow!\u2122 Technology instruction sets"
it's a bit vague :) But I do think that the "pentiummx" binary
is the most appropriated for your purpose. The Geode processor
seems to be "better" than an old 386 :)
If you are planning to *use* freenet on this chip, I do
recommand that you try building your own native library. I can
help you with that if you manage to pick me up on IRC (#freenet
on irc.freenode.net). It shouldn't be a big deal if you have a
working C compiler, gnu/make and a working jvm.
Try benchmarking different native binaries on your chip :
java -cp freenet-cvs-snapshot.jar:freenet-ext.jar net.i2p.util.NativeBigInteger
using the .7 code
