I would first rely on Heikki's suggestions and the MySQL Doc's as a starting point to create the initial PHP script. Then pass it around to a few knowledgeable MySQL people and they can run it on their machines to see how accurate it is. The PHP code will be open source so it will keep getting refined over the next few weeks. Eventually it will be posted on a website (MySQL? or InnoDb?) for everyone to try out. It will of course display a disclaimer saying this is what you should start with and further refinements may be necessary. But I think this will be a start in the right direction. It will get more an more accurate as time goes on and will give novice users something to start with. Brent --- Mike Wexler [EMAIL PROTECTED] wrote: I don't think this will work.

I don't mean to make any doc authors feel bad but there's something that don't match up on the InnoDB setup page. Exactly. There are too many places to find the tweaking documentation. In addition to the Performance Calculator page, there could be pages on manual tuning. I'd like to see the tuning docs in one location. Not just the ones from MySQL doc's or InnoDb, but from other sources as well. I do not know PHP but if there's some way I can help with this I'd be willing to try and pitch in. If there's at least one or 2 gurus out there would could answer questions one at a time, I could maybe start by making a list of what the page needs and what it should do for at least some of the values. If you'd like, I could write a static page with forms for the server-info to save some PHP coder at least that much time. What do you think? There are several steps to designing the MySQL Performance Calculator: 1) We should determine what input we need to collect and what output we need to produce (form design). We need to keep it simple for now then expand on it later. I definitely want to include InnoDb tuning too. 2) Once we have the form fields, someone can knock together the PHP form (me?), get it ratified among the participants. 3) Then do the underlying calculations for it and generate the output. 4) Once the calculations are done, we can distribute the PHP code within the group for people to test it. 5) When it is working satisfactorily we can post it up on a temporary site to see how it stands up. We will need someone to host it for a few weeks while we get the bugs out of it. 6) Once it passes scrutiny, then perhaps it can get posted on MySql.com. It all depends of course how good it is. If you would like to participate in choosing the form design, or calculations, testing, or temporary hosting, then please e-mail me directly. I don't think we'll get anywhere if we do it publicly because we'd get everything including the kitchen sink thrown into it.g We need to keep it simple to start with then build on it from there.
