Yes still working on this.
I don’t know anything about memcache. But will look into it. Suggestions are welcome.
Since Saxon/C v0.2 I have been working on improving performance.
Some benchmark results of Saxon/C vs libxslt in C++ are presented in the paper "Benchmarking XSLT Performance” from xmllondon 2014.
In conclusion we observed Saxon/C performed on average 0.5 to 2 times faster than libxslt on a set of xslt 1.0 stylesheets where we were doing file to file transformations. The two are comparable.
Is it possible for you to send me your stylesheet(s) and source documents so that I can analyse the performance at my end.
Should not be too difficult if we can get a proof of concept working in C/C++ with Saxon/C.
No real plans are in place, but to provide Saxon core features on the C/C++/PHP environments. But of course performance is important to us, ff there are clear opportunities to gain on performance I am sure we will pursue it.
Thanks for your understanding
