Yup - that makes sense. Fetching data will always be the bottleneck to any website. I realize that with the added ease that we get by using EOM and not writing any SQL, you now have me thinking/wondering how much of a penalty are we talking about here?

Well... practically speaking... and as you rightly pointed out... "Fetching data will always be the bottleneck"... and this stays true with or without EOF... EOF is not a magic bullet... even if it may makes your life easier... and in the grand scheme of things... EOF doesn't add much overhead if you take into account the entire request/response loop...

In any case, here is an handy diagram for your perusal which illustrates what's happening when fetching data through EOF:

This particular project isn't going to have to worry about past projects performance metrics, but a future project might. Do you (or any lurkers) have thoughts on performance difference? Sorry if I'm coming across paranoid, I just really wish to understand the real-world performance of WO so that I can plan or design > accordingly.

The bottom line as far as "performances" goes is that if you have a sane design in the first place everything else will follow. But this has nothing much to do with EOF in and by itself. Obviously you shouldn't fight whatever toolkit you may choose to use [1], but that's a secondary issue.

Cheers,

PA.
