accomplish output buffering in ofbiz

[Tim McGuire]

I have a report done in freemarker that is slightly more than 2000 rows.
I manipulate it with maps inside of maps and it bogs down the browser
and my system when I run the full report.  When I chop away all the
freemarker Map manipulation stuff and just dump the 2000 rows to the
screen, it runs much faster, so I'm looking for a way to make my
freemarker more efficient.  I've tried replacing maps with html strings,
but it does not seem to help.

Can ofbiz do output buffering?  If not, how should I approach this
issue?
Thanks.

here is part of .ftl file:
(completionMap has 2271 members.  $person right now ends up being a
string with the data rendered as a row in the report - just to see if it
speeds up.)
I believe the issue is with object wrapping but I don't know enough
about it to know how to fix it.

     <#assign completionList = completionMap.keySet() />
     <#list completionList as key>
     <#assign person = personInfoMap[key]>
     <tr>
         ${person}
        
     </tr>

</#list>
