> Key: WEEX-648
> URL: https://issues.apache.org/jira/browse/WEEX-648
> Project: Weex
> Issue Type: Improvement
> Components: Android, iOS
> Reporter: xingZhang
> Assignee: xingZhang
> Priority: Major
>
> We will introduce native batch for dom operations generating from javaScript
> wrap a series of dom operations with beginBatch and endBatch directives, when
> every V-sync signal comes, we ensure that the operations between beginBatch
> and endBatch can be performed in current V-sync, this policy can drop frames
> maybe, for our policy dropping frames, we only allow 20 frames at most.
