[OpenLayers-Users] Huge amount of data crashing browser

[Pedro Baracho]

My data can be displayed via WMS. It represents the streets of my city and
is composed by a huge number of center lines.

I am currently using BBOX strategy and it is insufficient.
I am going to check cluster strategy. Do you know how can I use it to
display lines instead of points?
