Angular-calendar: Week view is slow

[sylvain-fr]

The week view is slow.

Even on online demo the week view is much slower than the month view. It takes 1 or 2 seconds to change week. On my environment it takes one more second.
Is there a way to improve it ?

Versions

• @angular/core:Current online version
• angular-calendar:Current online version
• Browser name and version: chrome 73

I noticed that too (https://github.com/mattlewis92/angular-calendar/issues/922) and found the culprit to be hammerjs, adding all the tap handlers for each segment of the week view turned out to have quite a perf hit. Are you using hammerjs by any chance? Also do you use the hourSegmentClicked output? I can probably disable adding the tap events if the hourSegmentClicked isn't set, and maybe even lazily initialise the listener using requestIdleCallback which should take care of the worst of the performance issues which are causing that initial render lag.

I just released 0.27.3 which makes things a lot faster now, on the demo the initial render of the week view is <200ms 🎉 Everything else in the profiler was just DOM elements rendering, so maybe when ivy is stable this will get even faster 😄
