Might deleting my rich client cache improve performance?

In some cases, deleting the rich client cache may improve Teamcenter performance. To improve performance and tailor the user experience, the Teamcenter rich client caches information that is local and specific to each user. The cache includes information about session windows, current plug-ins, system configuration, dialogs, display preferences, and so on. However, in the following situations, contents of the cache can degrade performance: When a plug-in is updated with new or modified code, the cached information does not match the new or modified plug-in, and the client may not work properly. When a user opens thousands of items, the current application can become slow to respond. The next time that user logs on to the rich client, the system attempts to open the previously accessed items and can take a long time to complete the startup. In these situations, removing the cache is recommended. The cached information can be safely removed because the client regenerates any needed information when the user next logs in. Caution If TCCS advanced configurations are enabled, a TCCS configuration (cfg) directory exists within the ...\Siemens cache folder. While user cache files can be deleted, the ...\Siemens\cfg configuration directory must not be deleted or TCCS will stop working correctly. When TCCS is configured for The configuration directory is here Windows operating system Linux operating system Public (shared) C:\ProgramData\Siemens\cfg /etc/Siemens/cfg Private C:\users{USERID}\Siemens\cfg $HOME/Siemens/cfg
