Simply put, fetch() uses output buffering, display() does not. There was a discussion about this before, in the smarty-dev mailing list I think. It would seem at first that avoiding output buffering would speed things up, but in some situations the opposite may be true... such as with Apache and how it buffers its output.

If you are using Apache, try putting this in the httpd.conf:

Code:
SendBufferSize 65536


Or a size at least the average size of a web page from your server. This will force Apache to accumulate this amount of data to its output buffer before sending to the client, essentially what fetch() is doing for you at the application level anyways so no sense doing it again in Apache. Caution must be taken, this can have ill effects on low-memory systems (as would using fetch() on large output). Read the various Apache tuning guides for details.

Yes, my web server uses Apache but I can't change the httpd.conf
My pages aren't so large (the largest is 28k). May I use echo $smarty->fetch(..)?
