The Python run-time will automatically install all dependencies declared in your requirements.txt file during deployment. The library loading delay impact on start-up time is usually negligible; it may become a problem though, for instance in case of large third-party libraries. Related information may be found on the "Using Python Libraries" documentation page <https://cloud.google.com/appengine/docs/flexible/python/using-python-libraries> .
You have some means at your disposal to speed up your instance start up, such as using warm-up requests, lazy-loading your imports, or in the most extreme case, pruning your dependency tree. More detail on the subject may be found on forum articles such as "Best practices for App Engine startup time: Google Cloud Performance Atlas" in the Google Cloud Platform Blog <https://cloudplatform.googleblog.com/2017/06/best-practices-for-App-Engine-startup-time-Google-Cloud-Performance-Atlas.html> . -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
