In real world, processing a million points in a browser doesnt happen. 
JS is slow, download time is slow, execution environment in a browser is 
extremely limited. (in my experience, doing more than 1000 points of 
geometry is unacceptably slow in single threaded). Easiest approach for 
doing this in a browser begins with figuring how not to have vector 
data. If this is an offline application, you want to look at local 
server or local database. If you want to go extreme, then maybe look at 
html5 web worker api to go multithreaded but I suspect you are up for 
some pretty major rewrites of OL.
