| Subject: | findvalue from XML::LibXML 1.74 is very slow (regression) |
With XML::LibXML 1.74, findvalue is very slow, at least on large files.
See the attached testcase. Here are the timings on my Mac OS X 10.4.11
PowerPC machine, with XML::LibXML from MacPorts:
* 0.51s user time with XML::LibXML 1.70
* 6.04s user time with XML::LibXML 1.74
Perl version:
This is perl 5, version 12, subversion 3 (v5.12.3) built for
