Not much at all.
But, it is worth noting that your specific example will not really work.
Yes, data will get sent to the client, but as what you are sending is part
of a table it won't be displayed anyway until the entire table is retrieved.
That's how Web browsers handle tables, and there is not much you can do
about it (they display nothing until the entire table has been retrieved
because cells lower down in the table can effect sizing and spacing higher
up).
As a rule, this feature is useful for plain text, lists, complete tables,
etc - but not for partial elements.

Do we know what sort of processor hit it will cause yet? For example
would...
<cfoutput query...>
<tr><td>#name#</td><td>#phone#</td></tr>
<cfflush>
</cfoutput>
be painfully slow to be practical?
