Topic: painfully slow form rendering, especially with multiple select boxes

I have a rail 3.2.6 app on ruby 1.9.3

I have a view that has several forms on it.  It basically displays rows from the database into an html table with select boxes for changing the attributes.  The rows are not related to each other.   Each row displayed is its own form.   The rendering of this is very slow relative to the rest of the view.

I did find that fragment caching pieces of the form helped significantly but I don't want to implement caching where it shouldn't be needed.

Is this a common issue?  Are there notable ways of improving this performance?
