烧瓶应用非常缓慢

Question

I am currently developing an app that is served with a flask web server.

The back end python code has become extremely huge (to the tune of 1000 lines of code to give readers a perspective) with a lot of dependencies.

As a result, even simple api calls such as this:

@app.route('/', methods = ['GET'])
def hello():
    return "Sample"

results in the request taking close to 900 ms to serve.

Would anyone be able to give me tips on improving the latency? Would blueprinting help in this scenario?

The dependencies we have are all critical (we could perhaps remove one or two of them, but thats about it)...

Any help is greatly appreciated

Thanks, Galeej

Answer 1

Flask is a microframework for Python. It is not a web server.

A lot of reasons would cause a slow response. But I don't think dependencies or blueprinting is the problem. If you can provide how you deploy your app that would be helpful.

I think the most critical and simple thing is to log timestamp of each main process, then find which part cost a lot.
