lang=EN-US style='font-size:10.0pt;font-family:Arial;mso-ansi-language:EN-US'>If
anyone has any questions about the scalability of OpenCms, 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>

lang=EN-US style='font-size:10.0pt;font-family:Arial;mso-ansi-language:EN-US'>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>

lang=EN-US style='font-size:10.0pt;font-family:Arial;mso-ansi-language:EN-US'>Having
used packet sniffers 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
Javascript to render the page with the cpu load at 100%. The right-hand panel
html is all Javascript with the majority of it being one Javascript function
call for each of the 25,000 folders.<o:p></o:p></span></font></p>

lang=EN-US style='font-size:10.0pt;font-family:Arial;mso-ansi-language:EN-US'>I
have customized OpenCms heavily to support hundreds of sites running from the
same OpenCms instance and so it would take an effort on my part to upgrade from
the 5.0 RC1 base 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>

lang=EN-US style='font-size:10.0pt;font-family:Arial;mso-ansi-language:EN-US'>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>
