Hi,
In a previous message Berin talk about the xmlbench and how the c++
library was so slow.
Well I was keeping an eye over it to see if some new test results was
released(the last ones are from the beginnings of 2004), but for a
long time nothing happens. So I download the tests, patch it a little,
so it compiles in cygwin, and the java security test don't use xpath
as the plain c(not c++) don't use. and then pass the tests....
And the results are quite promising(xml-sec version is CVS HEAD at Jul
25th of 2005)
| xml-sec JUICE | xml-sec NOT JUICE | libxml1
xmlgen 4k | 4.51688 | 7.8826 | 1.985
xmlgen 256k| 41.03333 | 71.1916 | 102.175
opcgen 3.5k| 25929.0 | 41652.0 | 8747.773
opcgen 3M | NA | NA |61723.13
dmoz 12MB | 1239.5833 | 1675.0 | 1755.500
Signing/Verifying Time in ms
The data are quite good. In small messages we are more less 3 time
slower than libxml1. (if we increase the repetitions[from 4500 to
50000] the times gets better as JITS kicks in, but still not enough to
catch wit libxml [about 3.11582ms from 4.51688ms in xmlgen 4k] ).
But in medium we are quite right, better than libxml1. The only
problem is that we have some problem in opcgen 3M, I will investigate
it further and see if I can make this test pass.
Any way I'm quite happy with the results, I don't expect the numbers
to be so good. Taking on account that libxml seems so much faster in
the the xmlbench than xerces(two times), and the JIT wasn't helping,
it was shocking to see the numbers.
And also it looks it's time to put more effort into JUICE project.
Regards,
Raul
