Rails - Aug 2006 - RJS - slower than normal RHTML?

I know that isn''t supposed to be the case, and it usually
isn''t, but
today, I''ve run across a situation where rendering the same partial 
through RJS is taking about 5 times longer than rendering the partial in 
the RHTML.

I have in my main RHTML

<tbody id="account_transactions">
	<%= render :partial =>
''account_transactions/transaction'', :collection
=> @account_transactions, :locals => {:nobalance => false, :goto => 
false} %>
</tbody>

By putting a benchmark around just the render line, it renders on 
average 0.3 seconds.

Now I have a link on the page to go to another page (AJAX paging is the 
thought) and everything processes in a timely fashion except this line:

page.replace_html "account_transactions", :partial => 
''account_transactions/transaction'', :collection => 
@account_transactions, :locals => {:nobalance => false, :goto => false}


It continually takes about 2.1 seconds.

Does anyone have any idea on why rendering the same thing would take 
that much longer?  The collection contains 25 objects and for each 
object, two sub partials are rendered.

Thanks,
Trey

just a thought, but poge.replace_html not only generates the html from the
partial, but also a little javascript to actually do the work of the
replace. It also has to go through all the generated html and escape it i
believe, as it generates one long string which is used in the javascript
call..

I put a firebug console.time around prototype''s Element.update and it 
only took 128 ms.  It seems that it''s the render in the 
page.replace_html method call.  I''ll look further.
