Hi, I'm just looking at Koha potentially for a library here in our school. Congratulations to all involved and thanks for releasing it under the GPL. I have installed it and am tinkering about. It's on a 400MHz P2 w 128MB RAM running Debian GNU/Linux (sarge) in a MySQL database and I installed the sample data from sampledata-1.2.gz. The sampledata didn't insert entirely perfectly but it seems reasonable for testing. I was wondering about a few things. 1. The major book data seems to be in one table, including authors. I would instinctively have separated the authors into a separate table. Is this just a decision to favour simplicity over normalisation or am I missing something? 2. There are no indexes on the biblio table. Is this deliberate, did I lose something in installation or are we expected to add our own afterward? 3. The doc recommends not using mod_perl. Is this just because it's not tested or is there a more specific reason? I would imagine adding 4. It seems rather slow. Each search request is taking 3-5 seconds. The machine is running my desktop apps but isn't terribly stressed. I've tried using mod_perl and adding indexes but I get the impression that the time is mainly being spent within the perl code itself. Is this normal performance or have i done something wrong? Many thanks again for providing this system under the GPL. Hopefully it will save us a lot of time and effort. Gavin
