Issue/Introduction

We have an environment with a lot of hardware capability, but users have complained of slowness when using SDM.

Would we benefit from installing pdmweb_cache_sitemods option?
 - The PDMWEB Servlet, by default, does not cache files from the $NX_ROOT/site/mods folder. If this option is installed, files are cached from the sitemods folder.

Environment

Release : 17.x

Component : SERVICE DESK MANAGER

Cause

Environment with many customized web pages

Resolution

If the option is not installed, all files under $NX_ROOT/site/mods folder are retrieved from the directory each time one is needed.

So, if you have many customized web pages, or the customized web pages are frequently accessed, this option should improve the performance, improve user response times because the customization, it is cached in the pdmweb servlet. 
But this servlet is only used when the Web Interface is configured with Tomcat, not with IIS Server.
