Problem

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

Cause

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

Resolving the problem

The general recommendation for anti-virus settings is to exclude the Notes framework directories from scanning, especially the *.jar files contained in the directories. Excluding JAR files from real time scanning has shown significant improvements to 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.
