You are might be trying to resolve an issue that do not exist.</P><P>&nbsp;</P><P>There are multiple articles about investigating performance issues. You may want to look at your biggest performance issue in Production now instead.</P><P>&nbsp;</P><P>Sorry, I am not directly answering your question, I am afraid you are going down the wrong rabbit hole <span class="lia-unicode-emoji" title=":slightly_smiling_face:">🙂</span></P><P>&nbsp;</P><P>Philippe</P> Mon, 27 Apr 2026 05:42:39 GMT https://www.servicenow.com/community/sysadmin-forum/regarding-the-simultaneous-login-test-for-multiple-users/m-p/3532244#M22968 Philippe Casidy 2026-04-27T05:42:39Z
