That is what I suspected. I will call the Cheetah template in deferToThread.

Why not just compile your template at the head of the file using, Template.compile(file="path"). I did some experimentation with this, and it is very fast. Only time I could see where deferred would be useful is when you are compiling it initially, if you precompile your templates and dont call any blocking functions within it, it will be more than fast enough.

One other thing, rpy will automatically cache the instance you create if its in your resource class. Which means you will only take the hit once when initially creating class. So it may block briefly depending on size of template, but afterwards, should be as fast as calling request.write on a class directly, which is basically what your are doing.
