<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D;mso-fareast-language:EN-US">Thanks for your reply.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D;mso-fareast-language:EN-US">I don’t have any transparency on the config of our network so I can’t answer that. It is possible that my frustration peaks in the
afternoon and it is possible that is a red herring.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D;mso-fareast-language:EN-US">Each user has a similar project that contains tables in a SQL database. We need to add and edit items in these tables but struggle
when more than one person is editing in the same table.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D;mso-fareast-language:EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D;mso-fareast-language:EN-US">What I do know is that the refresh – or my ability to edit and save data - in the attribute table slows down when multiple users are
editing the same table. And I know that this behaviour has become worse now that we are all working from home and have the added ‘hops’ in the network created by our home Wi-Fi and VPN.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D;mso-fareast-language:EN-US">Our workaround today will be to try to make sure that only one person is in a particular table at a time.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-family:"Arial",sans-serif">The reason I'm keying on this is that one possibility is that your network infrastructure is slightly insufficient for the morning load and completely insufficient for the afternoon load.<o:p></o:p></span></p>

<div>
<p class="MsoNormal"><span style="font-family:"Arial",sans-serif">On the contrary, if your database is starved of resources, why is it worse now than when you were working from the office? Again your IT people should be able to look at log info or otherwise
instrument your server to find out if it's the problem (having suggested this I admit I wouldn't use SQL Server and know nothing about tuning it).<o:p></o:p></span></p>
