Takes a long time for onScroll to fire

I have

<div class="search-results" 
    infiniteScroll 
    [infiniteScrollDistance]="2"
    [infiniteScrollThrottle]="500" 
    (scrolled)="onScroll()">
</div>

When I scroll to the bottom, it somtimes takes 4 seconds for onScroll to fire.

I’ve tried all kinds of values for infiniteScrollDistance. With a high value, it works initially, but after scrolling for a while, the problem is back.

I experienced this issue also in Chrome (OS X), but not in other browsers. Happens still with new 0.8.1. It seems that the problematic part is the sampleTime() as adrienverge found out above. I think the root cause might be this: https://bugs.chromium.org/p/chromium/issues/detail?id=661155

sampleTime() uses timeout and while scrolling - especially rapidly with track pad - the events won’t arrive. After the scrolling is stopped, it takes couple of seconds and everything is working again.

I wonder if the semantics of the scroll throttle option could be changed a bit, so that 0 would leave the sampleTime() part out totally?

I have opened https://github.com/orizens/ngx-infinite-scroll/pull/235, it solves the problem for me when using [infiniteScrollThrottle]="0".
