When there are for example 600 records in your DB and you init/start your app with

DataStore.configure(awsConfig)

DataStore.observe(Quiz).subscribe(Quiz => {
console.log(Quiz)
})

The first time all the records are loaded. In seems like in chrome it's working well and in Safari there is some idle time and looks like your application crashes, your app continues working after all the records are loaded.

Anyone?

Hi @rpostulart

I am working on some performance improvements on the DataStore, if we don't encounter issues or problems, we are targeting next to release them.

I just tested a DataStore app with an API returning 100k items and it worked fine on Safari, so hopefully these fixes will make the issue go away for you.

Thank you for the patience

Hi good to hear, but were you also able to reproduce the issue / did you noticed the performance issue?

Hey @rpostulart

We just published new versions to the unstable npm tag with a bunch of improvements, it would be great if you can take a look and try them
