I have similar issues on a site I’m developing. I think @herry is onto something.
Why not create a simple mechanism for lazy loading repeater items on request?
This could be activated using a filter and would hide all of a repeters fields until a “show fields” link is clicked.
This should be pretty easy to implement and we would be able to stop ACF from loading and saving hundreds of files every time a page is edited.
It would solve all (most) performance related problems that backend users are experiencing due to having to many repeater (or equivalent) fields.
You need to include this on your page:
<style type="text/css">
.acf-map {
width: 100%;
height: 400px;
border: #ccc solid 1px;
margin: 20px 0;
}
</style>
<script src="https://maps.googleapis.com/maps/api/js?v=3.exp&sensor=false"></script>
<script type="text/javascript">

Then use this code when you want to display the map
<?php
$location = get_field('access_map');
if( !empty($location) ):
?>
<div class="acf-map">
<div class="marker" data-lat="<?php echo $location['lat']; ?>" data-lng="<?php echo $location['lng']; ?>"></div>
</div>
<?php endif; ?>

Me to!
Last night i dreamed that ACF Pro and WPML were fully compatible.
In my dream i just created some fields, connected them to my home page and when I visited the translated version of the page the fields were there.
With shaking hands I filled out the fields and submitted the page.
My fingers trembled as I clicked the “visit page” link and my heart was filled with utter and complete joy when I saw that the data showed up on the front end.
Oh what a beautiful dream it was.
