Some quick performance comparison results between mod_sed, mod_line_edit and
mod_substitute.
Search/Replace string : s/hello/hi/
test0.html : No matches, so no substitute.
test.html : 1 comparision/substitute
test2.html : 500 comparision/substitute

$ ab -c 200 -n 100000 <http-uri>
Requests Per Second (RPS) as measured by ab for s/hello/hi/ substitution.
mod_sed mod_line_edit mod_substitute
test0.html 3263 3206 3129
test.html 3229 3213 3197
test2.html 1278 404 1130
Note that mod_sed performs better than either mod_line_edit or mod_substitute.
Here is the configuration :
--------------------------
Alias /testsed/ "/usr/local/apache2/htdocs/testsed/"
LoadModule sed_module modules/mod_sed.so
<Directory "/usr/local/apache2/htdocs/testsed">
Options FollowSymLinks
AllowOverride None
AddOutputFilter Sed html
OutputSed "s/hello/hi/g"
</Directory>
Alias /testled/ "/usr/local/apache2/htdocs/testled/"
LoadModule line_edit_module modules/mod_line_edit.so
<Directory "/usr/local/apache2/htdocs/testled">
Options FollowSymLinks
AddOutputFilter line-editor .html
AllowOverride None
LERewriteRule "hello" "hi" [R]
</Directory>
Alias /testsub/ "/usr/local/apache2/htdocs/testsub/"
LoadModule substitute_module modules/mod_substitute.so
<Directory "/usr/local/apache2/htdocs/testsub">
Options FollowSymLinks
AllowOverride None
AddOutputFilter SUBSTITUTE html
Substitute s/hello/hi/
</Directory>
