I think that we decided that changes to the compliance engine were to blame; that eQUEST is slow when you have selected one of the compliance modes (like Title 24) and that it runs normally when not in compliance mode. I haven't thorougly tested, but that was our theory. If this is the case for you (maybe not if you're in Toronto?), it seems that you may just eventually need to put up with the sluggishness, but one way to partially get around it is to change the compliance version to "none" while you are working on editing the model in detailed mode, and then put it back to your compliance mode closer to the end when most of your inputs are complete. <br><br>Didn't reply to the full list because I'm not positive this is a real fix/workaround but let me know if it works for you.<br> <br>Hwakong <o:p></o:p></span></p><div class=MsoNormal align=center style='text-align:center'><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'><hr size=2 width="100%" align=center id=stopSpelling></span></div><p class=MsoNormal style='margin-bottom:12.0pt'><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'>From: BTysoe@mcw.com<br>To: equest-users@lists.onebuilding.org<br>Date: Thu, 19 May 2011 14:05:43 -0400<br>Subject: [Equest-users] Multithreading<o:p></o:p></span></p><div><p class=MsoNormal><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'>Hello equest-users,<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'> <o:p></o:p></span></p><p class=MsoNormal><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'>Does anyone out there know if the next release of eQuest (based on a new version of DOE 2 I believe) will be able to make use of processor multithreading?<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'> <o:p></o:p></span></p><p class=MsoNormal><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'>We are running into problems modelling large buildings with eQuest 3.64.
