Rasa X startup delay

Rasa version: 1.0.1

Python version: Python 3.6.8 |Anaconda

Operating system (windows, osx, …): Ubuntu

Issue:

n_stories = 3 (stories.md)
n_intents ~= thousand (nlu.md)

plus some regex features

With rasa train, it takes only 40 seconds to train both nlu and core and the resulting model size is 12 MB. But when I run rasa x, it takes more than 2 minutes to load the UI. As this is happening, a file named rasa.db-journal gets created and deleted at least a hundred times. sizes:

rasa.db = 1.6 MB
tracker.db = 1.6kB
model.tar.gz = 12.1 MB

It may be due to rasa.db-journal getting created and deleted a lot of times but I am not exactly sure what’s causing that. Any ideas why this might be happening? Thanks,

You are welcome.

Done @akelad. I love Rasa!

@psds01 I won’t be able to share the diff or PR unfortunately, as rasa x is not maintained as a public repo. The change was related to the frequency of SQL commits.

We’ll be releasing a new patch this evening (0.19.2) which improves the data injection speed further
