You mean the link texts to IP-Secrets and Bild.me? Those are SRWare's mutual web services so it is normal for them to be promoted on Iron's default search engine page (Ironstart).
I find them occasionally useful. For instance when I am being connected to the Internet under VPN, IP-Secrets can be used to confirm if the masking really works. We can change Ironstart anytime we like, of course. In fact, I don't use it myself.

Regarding speed, I have ever found some reports that Iron is the fastest Chromium-based browser. But it has never really bothered me (whether Iron is faster or not than Chrome or Firefox). I am running on low bandwidth after all.
