hi,

I have a first version of a callgraph profiler for libxml/libxslt (https://bugzilla.gnome.org/show_bug.cgi?id=612186). With this I looked at profiles for applying the docbook stylesheets. These are the topmost entries:

index % time self children called name 0.043 0.380 1947/3287 gentext.template.exists [4] 0.002 0.397 234/3287 *[object.title.template] [49] 0.380 0.380 1071/3287 gentext.template [0] 0.000 0.397 17/3287 part[object.title.template] [90] 0.000 0.397 18/3287 chapter[object.title.template] [102] [0] 33.26 0.380 0.380 3287 gentext.template [0] 0.380 0.380 1071/1071 gentext.template [0]

----------------------------------------------- 0.009 0.149 786/3967 *[find.chunks] [19] 0.010 0.154 738/3967 href.target.uri [18] 0.012 0.241 754/3967 *[chunk-filename] [16] 0.056 0.202 1638/3967 *[recursive-chunk-filename] [2] 0.001 0.136 35/3967 in.other.chunk [76] 0.001 0.173 16/3967 process-chunk [55] [1] 11.84 0.135 0.000 3967 chunk [1]

lines with [x] in begin are the templates. lines above the callers, lines below the callees. Any idea how to make gentext.template less slow? Or make it called less often. There sees to be many: match="*" mode="object.title.template" and match="*" mode="object.title.markup" leading to it, but I can't see any template that uses e.g. mode="object.title.markup"? Any ideas?
