Equally important to understand is that no matter how you update a web page, when you make changes to its (X)HTML content the parsing and rendering engine in the browser needs to update its internal representation of the page (recalculating the flow and layout) and then render the changes to the browser window -- for complex pages or changes this can take a considerable amount of time. MSDN's <a href="http://msdn.microsoft.com/library/default.asp?url=/workshop/author/perf/dhtmlperf.asp">DHTML Performance Tips</a> is a good overview of DHTML performance</blockquote></div><div style="margin: 0px 6px 6px 4px;"><table style="font-size: 11px;border-spacing: 0px;padding: 0px;" cellpadding="0" cellspacing="0" width="100%"><tr><td style="background:transparent;border-width:0px;padding:0px;">&nbsp;</td><td align="right" style="background:transparent;border-width:0px;padding:0px;width:107px" width="107"><a href="http://clipmarks.com/share/85D2BF65-57ED-4ADF-86B1-DB234FE77C96/blog/" title="blog or email this clip"><img src="http://content7.clipmarks.com/images/c2b-foot.png" border="0" alt="blog it" width="107" height="17" style="border-width:0px;padding:0px;margin:0px;" /></a></td></tr></table></div></div>
