This chart has 3 series with 32k points each.

It is rendering pretty fast (3-4 seconds including loading of the data) on Chrome 16/17 (Linux + Mac) and Opera 11.6 (Linux + Mac).
It is taking up to 30 seconds to render with Firefox 9/10 (Mac + Linux) (also getting a popup about a slow running script).

Highstocks problem or Firefox problem?

At least the script timeout pop alerts indicate that control should be given back to the browser from time to time using setTimeout()
