Forum:Server loading due to complex templates?

There are some templates such as Template:If that a few years ago ran into objections of server loading. Is it no longer the case that we should be concerned about server loading from recursive and other complex templates? If it is still a concern, then I will be more attentive to such templates that appear to be unaware of efficiencies possible from parserfunctions (eg in the above template's case, the #ifeq test for undefined parameters). ~  Ph l o x  20:14, 27 September 2007 (UTC)
 * Sorry, i dont know well that template, but i think they were unefficients and that was the reason to develop the parser functions extension. I use parser functions a lot on the french guild wars wikia... TulipVorlax 04:16, 28 September 2007 (UTC)
