Gwen:
The new Judy (probably rev 2.0) is going very slowly. I am having problems
debugging it quickly,
while testing the effects of modifications on speed. So, I decided to use the
1.0.5 version of Judy
to try some of the speed fixes. There is one "fix" to "JudyGet.c" that
improves the speed about
50%. Some of the others changes require many file changes. I will make that
one "fix" and send
you the source to try out, if you are interested. I will incorporate some of
the other changes
in rev 1.0.6 when I know how to use "popc" in Windows and Apple compilers.
Perhaps, I
will only use it in the 64bit versions (or until Core 2 duo becomes obsolete).
I only use one SSE instruction in the new Judy so far -- popc (bit counting).
I would be very interested
to knowwhat other you use to get the %20 speed gain.
Thanks for you interest,
doug
