Hi folks,
Anyone have a guess on whether or not having a lot of displays (block/page) in a View can slow down the site or have any other negative consequences?
I'm wondering if I should make one BIG View with probably at least 30 block displays, or if I should make them into separate vocabularies and smaller Views.
What do ya'll think?

I suspect that it makes no
I suspect that it makes no difference, but I haven't specifically tested. Only the code for a specific display is run when that display is called. If block and views caching is properly configured, views displayed in blocks should have reasonably low overhead.
What multiple displays give you is the freedom from repeating the same configuration. If you have a display where every piece of the base view is overridden, it should be a separate view.
Thanks!
Thanks for the info, highermath. I appreciate your insight.
on large sites perhaps
Further info to the topic ...
We have a large D6 site with quite a few views. But recently creating one large one of about 100 feeds. The site itself functions fine, but we are having issues with some of the backend admin functions. Like saving views or taxonomies, as it runs out of memory. Currently breaking it up into smaller views of 25 feeds each to see if that helps.

ie.
In the other hand, having multiple displays in one view that contains mostly overrides will be a burden to the system and will be hard to maintain. The effect of having only couple of such displays has negligible performance difference. It will be magnified when the number of displays in one view is large.
