I recently worked on a very large site where it took between 6-12 seconds (in chrome) before the node/add|edit/page was loaded. We assumed at first it had something to do with the multiple CKeditor instances on the page but after looking at the problem more closely we found out the (collapsed) token-placeholder table being generated was 6MB in HTML data (I kid you not).
Now, this isn't your typical site as it has 40 content-types and about 30 views and I know there's very little you can do about this, but I'm just throwing this out there if someone googles for having slow node/add|edit/content-type pages after adding viewfield.

jerdavisThe suggestion of adding a configuration option to enable/disable the token help was suggested here:
#2299687: Conflict with LinkIt caused by Viewfield placeholder tokens list
Switching this to a feature request and assigning to 7.x-3.x

jerdavisAfter reviewing other issues and considering the updates to Token since this was originally opened, I don't believe this still poses a problem. The token tree is loaded on demand once the link is clicked, rather than loading a giant table on add/edit of a node.
