It has been a while since the Socket Benchmark of Asynchronous server. That benchmark looked specifically at the raw socket performance of various frameworks. Which was being benchmarked by doing a regular HTTP request against the TCP server. The server itself was dumb and did not actually understand the headers being send to it. In this benchmark i will be looking at how different WSGI servers perform at exactly that task; the handling of a full HTTP request.
"I was reading David Cramer's tip to use JSONField in Django to be able to store arbitrary fields in a SQL database. Nice. But is it fast enough? Well, I can't answer that but I did look into the difference in read/write performance between simplejson, cPickle and marshal."
