Notes client startup performance is slow when JAR files are set to be scanned by anti-virus

Technote (troubleshooting)


You notice Notes client startup is taking a long time when real-time scanning of Notes program directories is enabled.


In some cases, this issue is due to anti-virus software scanning the .jar files contained in the Notes/framework/ directory.


Notes 9.0, Notes 8.5.3, multi-user, Windows 7

Resolving the problem

The general recommendation for anti-virus settings is to exclude both the "notes\framework" (especially the *.jar files) and "notes\data\workspace\.config\org.eclipse.osgi" directories from scanning.

Depending on how the client was installed, it may be feasible to instead exclude the whole "notes\" directory, if Notes was installed to its default location on the OS, or exclude both "notes\" and "notes\data" separately, if custom installed. These main directories will include the sub-directories noted above.

For example, the default directories for installing Notes 8.5.3 multi-user under Windows 7 are:

Notes programs c:\Program Files\IBM\Lotus\Notes
Shared resources c:\ProgramData\Lotus\Notes\Data
User data c:\Users\<user name>\AppData\Local\Lotus\Notes\Data

Default directories for installing Notes multi-user under Windows 64bit OS:
Notes programs c:\Program Files (x86)\IBM\Notes\Data
Shared resources c:\Program Files (x86)\IBM\Notes\Data
User data c:\Users\<user name>\AppData\Local\Lotus\Notes\Data

The above directories would exclude the jar file scanning, excluding jar files from real time scanning has shown significant improvements to Notes startup. Any kind of real-time scanning of the Notes program directories before startup will impact upon the performance of the client as it starts.
