agreed.  i wasn't saying that the use of custom tags were the culprit in the
other sites.  all i can talk about is what made a difference in the sites i
was working on.  one of the performance tweaks that made an improvement was
to reduce the use of custom tags.  there are others, but that's the only one
that relates to this thread.

> You've seen custom tags cause memory problems?

no, that's not what i said.

not once or twice within the same request, but even a well-written custom
tag that's called inside of a loop and executed many times in a single page
request can cause the page to be executed slower than if the action the
custom tag performed was done directly in the template or an include.

uh, i was referring to the variables scope in general.


you'll get "NO" as the output.
