+Saving a wiki page in ikwiki or
+<tt>ikiwiki --setup wiki.setup --rebuild</tt> takes a **dozen minutes** on a tiny tiny wiki (10 user-added pages)!
+
+I profiled ikiwiki with [[!cpan Devel::SmallProf]] : see [[users/mathdesc]] for details.
+
+And I came to the conclusion that filecheck on attachment was the only cause.
+It always go the fallback code using time-consuming file even there it's look like it's
+not successful.
+
+<pre>
+ # Get the mime type.
+ #
+ # First, try File::Mimeinfo. This is fast, but doesn't recognise
+ # all files.
+ eval q{use File::MimeInfo::Magic};
+ my $mimeinfo_ok=! $@;
+ my $mimetype;
+ if ($mimeinfo_ok) {
+ my $mimetype=File::MimeInfo::Magic::magic($file);
+ }
+
+ # Fall back to using file, which has a more complete
+ # magic database.
+ if (! defined $mimetype) {
+ open(my $file_h, "-|", "file", "-bi", $file);
+ $mimetype=<$file_h>;
+ chomp $mimetype;
+ close $file_h;
+ }
+ if (! defined $mimetype || $mimetype !~s /;.*//) {
+ # Fall back to default value.
+ $mimetype=File::MimeInfo::Magic::default($file)
+ if $mimeinfo_ok;
+ if (! defined $mimetype) {
+ $mimetype="unknown";
+ }
+ }
+</pre>
+
+Any ideas , solve :) more that welcome.
