A special linux distribution for developing OLPC applications

[Jim Gettys]

Rob,

If you know a glibc hacker, there are Geode optimized functions for some
of our basic string functions found at
http://dev.laptop.org/git.do?p=geode-perf;a=summary

Some of these are significantly faster than what is currently in glibc.
We've not had time yet to see about integrating them.
                               Regards,
                                 - Jim Gettys
