The issues don't really change. Opening 1000 concurrent connections means spawning 1K PostgreSQL processes, which will reserve a pile of memory, and cause a pretty severe performance problem. It is _vital_ that your application uses some form of "connection pooling" so that it can share 50-100 connections across the requests rather than opening 1K connections. How that is done will depend on your favored web application framework. Most frameworks have some notion of a "connection pool," so this certainly shouldn't need to be a crippling problem. -- (format nil "~S@~S" "cbbrowne" "ntlug.org") http://cbbrowne.com/info/lsf.html Rules of the Evil Overlord #75.
