font-family:Arial'>If anyone has any questions about the scalability of <span
class=SpellE>OpenCms</span>, we have an installation with over 25,000
directories and the run-time system performs excellently for hundreds of
thousands of pages and a hundred or so different sites all on one instance.<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'><o:p> </o:p></span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>However, this size of installation does have some problems
on the authoring side. The time taken to lock a file, for example, with
Netscape is about 30 seconds. With Internet Explorer it is a whopping two and a
half minutes. (All operations that result in the right hand explorer panel
being redrawn all take about the same length of time.- lock, unlock, return
from the edit window, return from the Admin pages, etc.)<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>Having used packet <span class=SpellE>sniffers</span> I find
that all the data is returned from the server in about two seconds. The rest of
the time is spent in the browser running <span class=SpellE>Javascript</span>
to render the page with the <span class=SpellE><span class=GramE>cpu</span></span>
load at 100%. The right-hand panel html is all <span class=SpellE>Javascript</span>
with the majority of it being one <span class=SpellE>Javascript</span> function
call for each of the 25,000 folders.<o:p></o:p></span></font></p>

font-family:Arial'><o:p> </o:p></span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>I have customized <span class=SpellE>OpenCms</span> heavily
to support hundreds of sites running from the same <span class=SpellE>OpenCms</span>
instance and so it would take an effort on my part to upgrade from the 5.0 RC1 <span
class=GramE>base</span> that I’m using. However, have there been advances
in the client-side explorer window code that might speed up things? If so I
will certainly take the time to do so. Any other ideas would be appreciated
too.<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>Some more information is that I can’t easily separate
the system into multiple authoring instances because of the sharing of pages
and page elements. I tried projects but although a project may only have a few
hundred folders, it still displays the entire tree.<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>If the <span class=SpellE>OpenCms</span> team is interested
I have a fairly detailed analysis of what is going on with this size of system.<o:p></o:p></span></font></p>
