Good stuff, Daniel... Thanks for taking the time to tabulate the results and present them. If your results hold, it may have a significant impact on my application. I'm working on a Perl/XS port, and I think a lot of people who want to run it won't be running mod_perl, so startup times

I got the category thing to work. I'm using a string "category" that looks like: Cat1[980455981]{4}|SubCatA[980456122]{1}| Then I can search by id, name and when I get a result list I can put them in sequence (the soft bracket number) However, my problem now is distinct... I want to put items
