Performance issue when importing large ICS file

[arthurlutz]

Similar to cozy/cozy-contacts#89 when importing a "large" ical file (3000 events) cozy-calendar renders the browser pretty much unusable.

Thank you for reporting. That problem should be fixed too. We'll make some tests.

Hello @arthurlutz,

Is the problem during the import or afterwards when you use the application? Or both? Thank you for your answer, it will help us to prioritize.

I'm afraid it is both. This issue was reported mainly on the import side of things. The "after import" part is slow but does not freeze the browser.

Thanks, I am not sure we'll be able to fix it soon, but we are working on a generic solution for "big list" issues.
