I don't know if it is even that much faster when most of the delay is loading content anyway. I think that webview is well optimized for showing this kind of content and strfry performs really well.

Tere aren't that many native Linux clients either. For me Gossip was pretty unstable and crashed couple of times when I tried it. Don't get me wrong, noStrudel is no perfect either but haven't had it crashed like that.
