What about potential customers? I've been evaluating your platform and just be completely frustrated with 3 days wasted trying to solve these performance issues.

I'm using gunicorn with python, and if I use the sync worker the request queue easily hits 10 seconds and nothing works; if I switch to gevent or eventlet, new-relic tells me that redis is taking the same time stuck getting a value. This is using the same code in my current provider that works just fine with eventlet and scales well.

To add insult to injury, adding dynos actually degrades performance.
