Duo is slower...?
I saw the post about the removal of activity streams, for the purpose of the site running faster. However, the site seems slower to me (I know it's not me, I just did a quick search and I know it's not the same). I don't really know where this topic should go, but it's not really a "resolvable issue", so I guess that's why it's in the language section.

So what I am gathering is that Duo is getting rid of OUR activity streams without even asking us, and trying to make the site faster. That is why EVERYBODY today is not having a stream. THEY DIDNT EVEN ASK US. I have actually never had a stream, because I was always a part of an A/B test...
It seems slower only because you started paying attention to speed. A watched pot never boils.
Unless you've been measuring site's performance with appropriate tools for a long time, you can't really say anything. Hunches are unreliable.
The straw that broke the camel's back was a one-hour long lag spike, which almost brought down the entire site. If you weren't on Duolingo at that time, you missed the worst.
