We are currently working on these problems, that's why the site is unstable.
Thank you for having a little patience, the site is two weeks old, and faces more than 100 simultaneous visits in peak hour, 174 000 requests in 25 hours, 7GB of downloads in 3 hours.
We have neither the infrastructure nor the teams of facebook. I'm on my own with this, so I do what I can.
Things will improve quickly.
We know about the slowness issues, and having yet another discussion about it is not necessary or constructive.
