Bug #3443
Updated by Michael Kay over 6 years ago
A user has submitted an XSLT transform that takes 102s under 9.2, increasing to 241s under 9.8.
*Summary: the main problem was that with hotspot bytecode generation enabled (the default setting for Saxon-EE), a recursive function that was building a tree by making recursive calls to copy a source tree, was being executed in pull mode rather than push mode, resulting in an excessive amount of tree-to-tree copying.*
