In AWS, this kind of service is out of scope of support, but if you have luck to find an Engineer that knows SQL Server and is willing to help you, as I was, it will, help him or her to help you to tune the queries. You can help the support Engineer by sending him the queries that are breaking your system. There are plenty of times you need to do this, especially if you don’t have a full-time DBA or if you are running in the cloud and needs some support from the cloud provider. Whatever the query you prefer to use, the big question will be how to do it in real time when the problem is actually happening, and log whatever information you need, even on the unattended server. I will show how to do it using both (Michael J Swart – Identifying High CPU SQL Processes) One of these techniques, using Process Explorer, is very nicely described here by Michael J Swart: Note that he updated the post, explaining that now he uses sp_whoisactive. Yes, you don’t need to be in the front of your workstation you can check later and then perform whatever corrective action needs to be done in the light of the data you’ve captured. When it fires, the process checks if the source of the WMI event is SQL Server and then logs in and executes the statements for you. I am talking about a technique where you set up an event-driven solution that will be fired by a WMI event when the CPU is high, thereby avoiding pooling and jobs having to running every few seconds. It is like catching a close-up of a villain in the floodlights at the very moment of the crime. In this article, I will show you how to use both these tools and, especially, how to do it in real time when the CPU needle is ‘hitting the red’. I have my favourite techniques for doing this: I like to use both process explorer and sp_whoisactive to find the queries that are taking too much CPU in SQL Server, but I like to run them at the actual moment that the heavy usage happens, even if I’m actually at home relaxing. Beginning with SQL Server 2016, it’s become so much easier to monitor performance in SQL Server with Query Store, but there are plenty of techniques that are still useful to investigate SQL Server high CPU, particularly if you don’t have SQL Server 2016 Query Store on the database that you’re checking. There are plenty of ways of finding out what processes are consuming CPU, killing your database’s performance. In my case scratch pad has never caused an issue.SQL Server High CPU: Investigating the Causes - Simple Talk Theres also a possible fix they found for scratch pad issues in another thread here Maybe the performance monitor window (enable 'show devices' and sort by cpu) can help you find what is causing the difference. Though I do make heavy use of their excellent effects plugins (proeq, binaural pan, mixtool, reverbs, dynamics, etc) all my vsti's are 3rd party (kontakt, reaktor, iris, alchemy, etc.). I thought possibly that since my projects don't use any presonus instruments (like presence, sample one, impact, mojito etc.) its possible the difference in your expereince could be due to those instruments' updated versions using more cpu if your work uses those. The only difference I can find is the GUI's graphics drawing/update in v3 is much more prone to becoming laggy, (like low framerate) where v2 was much more fluid in general. I found every direct comparison to be exactly the same (within a percent) - in every case. I spent quite a few hours yesterday comparing cpu usage between v2.6.5 and V3 - from simple to complex songs - I noted cpu load during both idle and playback, and export time comparisons (which were all within a second of each other). It freezes after I'll send an arrangment from the timeline into scratch pad (from right mouse click send to scratch pad) other than that it's an awsome update. I hope this gets fix with in the next update. When opening it in V3 the CPU meter reads 100%. I'm constantly getting click and pops and its a session coming from V2. Arielacevedo wroteCompared to V2, V3 it is A LOT Cpu intensive.
