Whether you are running SQL Server on a physical or virtual machine the first step in diagnosing performance issues is to determine bottlenecks with most contention. Furthermore, virtualization servers quite often are built for size (plenty of Disk Space, CPU Cores and Memory) and not performance.

We would need to look at the Disk Transfers/sec, Average Disk Queue Length, and % Disk Time on the Host to see if there are any I/O contentions.

This is because from inside the VM we might not get the full picture. However, when SQL Server is running on a VM inside a Virtual Host the Disk I/O issues are not easy to detect and resolve. Microsoft Dynamics GP uses TempDB quite extensively, so moving TempDB to a faster drive can also provide performance boost. When running Microsoft SQL Server on Physical Hardware as opposed to a Virtual Machine (VM), performance issues related to Disk I/O can be mitigated by separating SQL Data & Log files to different physical disks. ELIMINATING DISK I/O PERFORMANCE BOTTLENECKS To avoid this, maximum memory available for SQL Server should be set up to 80% of the total available memory. If it’s left unlimited, SQL Server can end up with most of the memory not leaving enough memory and resources for other services and applications. Another problem with SQL Server is the maximum memory allowed for SQL Server. If it’s lower than 200 then more memory should be added to the SQL Server. One measure to see if enough memory is available is Page Life Expectancy (PLE).

This keeps the SQL Server from running into performance issues. The data that is queried is usually cached in memory. Having more memory on the system can reduce the number of I/O activity on the disk. Memory is most critical factor affecting SQL Server performance. On a virtualized SQL Server we also have the option to increase CPU Cores but should be done after expensive queries and indices have be reviewed. Looking up 5 to 10 most expensive queries via SQL Server Performance Report and adding appropriate indices can reduce the full table scans and improve performance. On the other hand if CPU has historically shown high level of utilization then the issue could be lack of indices or need to rebuild indices. This could be easily fixed by identifying the query and re-writing it. In regards to CPU that has shown low utilization before, and suddenly starts showing over 70% utilization the culprit is most likely a badly written query. Performance monitoring on the SQL Server will reveal higher CPU or Memory utilization, or intensive Disk I/O activity, or all of the above. SQL Server hosting Dynamics GP databases in such cases might experience delays in lookups, inquiries/reports as well as GP freezing or locking up from time to time.

Microsoft Dynamics GP implementations for midsize to enterprise level organizations with 30+ users and more than 1000 transactions per day fall into this category of high I/O and resource workloads. PERFORMANCE ISSUES WITH MICROSOFT DYNAMICS GP Whether you are using Microsoft HyperV, VMWare, Citrix XenServer or any other virtualization platform, SQL Server performance has been an issue especially for applications with I/O and resource intensive workloads.

However, when it comes to running Microsoft SQL Server on a virtualized environment the results have been mixed. Virtualization holds the promise of unlimited resources & computing power, and it has seen lot of success in virtualizing web servers, application servers, desktops etc.
