A 160MB KML file will no-doubt crash your user's browser!  The limit is not
with OL, it's a browser limitation trying to handle way too many DOM
objects.

Some alternatives include...

- Breaking up the single large kml into multiple smaller kml's and loading
them at different zoom levels
- Loading the data into a database and using a script to fetch only the
markers you need (via BBOX)
- Using GeoServer to serve the data via WFS or WMS
