as mentioned in the docs (http://doc.silverstripe.org/framework/en/3.1/reference/partial-caching) i thought, that using partial caching could also reduce the number of sql queries.
<% cached 'MenuLeft', List(SiteTree).max(LastEdited) %>
<% loop $Menu(1) %>
<li class="$LinkingMode"><a href="$Link" title="$Title.XML">$MenuTitle.XML</a></li>
<% end_loop %>
<% end_cached %>
When i check by using ?showqueries=1 the sql-queries stack is exactly the same?
Confusing (to me) ....

I'm not sure that this is the case here, because I've seen a some discussions of partial caching not always actually caching... But just a hunch: SilverStripe tries to cache many of its queries and objects along the way, so could it be that menu(1) already uses cached queries in the first place?
I often test these kind of things by placing some echo "*****" in the function involved, say at the start and the end of the function. Kinda simplistic and dirty, I know, (hiding my face) but quick to spot any sql queries executed by that specific function
