Gra=nt once told me that doing three lookups takes about the same
amount of resources as a single search ... so if you're doing
three or more lookups in a single db record you're actually better
off replacing them with a single search.

I seldom use lookups because I typically need data from more than
one field anyways.=C2=A0 And it's not possible to use lookups when the<=br>value you're seeking might not be an exact (case sensitive) match,
so this is another limitation of lookups that encourage me to use
searches more often.

I avoid nested contexts as much as possible too, because the more
nesting you employ the more resources are used.=C2=A0 Sometimes things
can get pretty slow when nesting too much ... :(

I generally prefer to avoid nesting by putting my search contexts
at the top of the page, then setting the values I need from the
founditems context as text vars.=C2=A0 This allows me to start and end
my search without nesting any other contexts inside.=C2=A0 Then when I
actually need the db values from the founditems context further on
down the page, they are all available as text variables.

I use text variables extensively and have never had a problem
setting hundreds or even thousands on a page.=C2=A0 I think the use of
text variables to avoid nested contexts, and using searches to
avoid multiple lookups, makes good sense.
