Something else was probably amiss in your set up? The only minor delay I noticed was during boot up, when dhcpcd started looking for a DHCPv6 server. However, just like IPv4 this process was backgrounded and therefore the delay was not significant, or even readily observable. In IPv4 only networks, no IPv6 DNS resolver was available and consequently there was no searching or delay on my PCs for IPv6 addresses. Incidentally, I observed a Windows 7 PC falling over itself when it was booted in a dual stack network with its IPv6 disabled.
