Knut Relbe-Moe presented on best practices for optimizing SQL Server performance for SharePoint environments. He provided 13 tips including using dedicated SQL instances, proper disk configuration including SSDs formatted at 64k blocks, adequate RAM and CPU, tempdb optimization, and recovery model configuration. The presentation emphasized following Microsoft's guidance and best practices for SQL Server installation and maintenance to ensure the backend database provides optimal performance for SharePoint.

- 4. Okay… Something is wrong with this picture…
- 5. MS SQL Server is like the brain of your SharePoint environment
- 6. So if the brain works slow, everything else will be slow….
- 7. 99.9% of SharePoint content stored in SQL Server Farm Configuration information stored in configuration db Central Administration content stored in seperate content db Most Service Applications have at least one db All Web Applications have at least one content db
- 8. How to fix this Follow the guidelines in this presentation Read and understand this whitepaper from Vlad Catrienscu Maximizing SQL 2012 Performance for SharePoint 2013 WhitePaper If you have to reinstall MS SQL server as a new instance with the correct settings.
- 9. Agenda Foundamentals 13 tips to get your SQL Spinning Summary
- 11. SQL Server configuration For SharePoint 2013: • SQL Server 2008 R2 SP1 • SQL Server 2012 (SP1 for BI) • SQL Server 2014 (SP2013 SP1 & April CU) For SharePoint 2016: • SQL Server 2014 • SQL Server 2016 Use a dedicated instance Run the service with a Managed account •No specific permission Use named instances SharePoint
- 13. Physical SQL Server will always outperform a virtual SQL server with the same specs, but what shall you choose. Pros : High availability because of the hypervisor, not because of clustering Easier to scale up & down Can be easier to recover at Disaster Recovery Cons: Very heavily loaded VMs have seen disk I/O issues Over allocation of a virtual host. If you have too much running on a host, it's not just I/O that could be impacted. Harder to protect Physical vs Virtual
- 15. DISKS You should invest in as fast disk as possible If you run on a Virtual Server, consider physical disks for the SQL server SSD or SAN If you have physical SQL server you should use at least 6 Disks: 1. TempDB 2. TempDB Logs 3. SharePoint Databases 4. SharePoint Databases Logs 5. OS 6. SQL binaries and other application Installs
- 16. DISKS • You have a farm where most of the content is only read and downloaded • Your users will be collaborating, uploading documents, content Speed/Scenario Read Intensive Scenario (ex Public Website) Fastest Tempdb data files and transaction logs . Database data files . Search databases, except for the Search administration database Slowest Database transaction log files Speed/Scenario Write Intensive Scenario ( collaborative workspace) Fastest Tempdb data files and transaction logs . Database transaction log files . Search databases, except for the Search administration database Slowest Database data files
- 18. RAM & CPU • Your SQL Server needs to have enough RAM to function properly. • If your SQL Server runs only SharePoint, here are the minimum requirements Small Farm Deployment (0-500GB of Data) Medium Farm Deployment (501-1TB of data) Large Farm Deployment (1-2TB of Data) Very Large Farm Deployment (2-5 TB of Data) Special Cases Ram Required 8GB 16GB 32 GB 64GB 64GB+ CPU 4 4 8 8 8
- 20. DISKS SQL server reads and writes 64k at a time So change your allocation size from the 4K default to 64K. This small change alone, will improve your SQL performance by up to 30% Use chkdsk <drive>to Verify Use Format to Configure: • Format <drive> /Q /FS:NTFS /A:64K /V:<volume> /Y
- 22. Server Configuration – Collation SharePoint server 2013 is built to use Latin1_General_CI_AS_KS_WS. This is a quote from Microsoft to prove it: “We support any CI collation for the SQL instance (for master, tempdb databases). However we recommend using Latin1_General_CI_AS_KS_WS as the instance default collation (master, tempdb databases).” CI – (Case Insensitive) A and a ARE treated as the same character. AS – (Accent Sensitive) a and á are NOT treated as the same character. KS – (Kana Sensitive) Japanese Hirakana and Katakana characters which look the same are NOT treated as the same character. WS – (Width Sensitive) Single-Byte and Double-Byte versions of the same character are NOT treated as the same character.
- 23. Server Configuration For SharePoint 2013: • SQL Server 2008 R2 SP1 • SQL Server 2012 (SP1 for BI) • SQL Server 2014 (SP2013 SP1 & April CU) For SharePoint 2016: • SQL Server 2014 • SQL Server 2016 Use named instances SharePoint Use a dedicated instance Run the service with a Managed account •No specific permission
- 24. Server Configuration Use alias for the connection string • Client alias or DNS alias (preferred) Good practice : every SP Content db must be created (and documented) by a DBA after a strict capacity plan
- 25. Server Configuration Use alias for the connection string • Client alias or DNS alias (preferred) Good practice : every SP Content db must be created (and documented) by a DBA after a strict capacity plan
- 26. Server Configuration Backups Compression
- 28. Thomas Larock from SQL Rockstar explains this: SQL Server (and other database systems such as Oracle and Sybase) need to read data pages into their internal memory before they can be used. Of course your server needs memory to operate as well. When your database engine and your server are competing for the same memory resources, you get bad performance. You want your server and your database engine to be like dancing partners, and less like my kids fighting over the last cupcake. Max Memory
- 30. Optimize TempdB Split across n locations N = total number of physical cores > super myth All temp files need to have the same size Size of largest content dB or 10 % of Total Content DB’s Size whichever is bigger The fastest disk possible | Place on a different Drive than the Content Database Simple Recovery mode Place on Different Drive Than Content Databases
- 31. Model Database SQL Server uses the Model database as a template for creating new user databases So therefor make sure that Model database have correct initial size and growth settings. The log should be around 25% of the initial size. The auto growth is your insurance policy if your current database size has been reached.
- 32. Script
- 34. Auto Create Statistics Do not enable auto-create statistics on a server that hosts SQL Server and SharePoint Server Enabling auto-create statistics is not supported for SharePoint Server
- 36. USE “DBA” created databases Sizing Autogrowth DO NOT USE SIMPLE RECOVERY Unless you understand the implications
- 38. Maintenance Plan Create a maintenance plan to backup databases, rebuild indexes and checking the logical and physical integrity of your database Make sure you don’t run backup when heavy timer jobs runs in the SharePoint environment, like midnight
- 39. Recovery mode Model db : recovery model = full Tempdb : recovery model = simple SharePoint DB : recovery model ? Contend DB = full Config DB= simple Services App DBs= it depends : •http://technet.micro soft.com/en- us/library/cc678868. aspx
- 41. Script your SQL Server installation https://sqlserverfinebuild.codeplex.com/
- 43. Always install SQL Alias in SharePoint Use alias for the connection string • Client alias or DNS alias (preferred)
- 45. Using SQL Server Resource Governor to optimize Search Database usage Part of SQL Server Enterprise (since SQL 2008) Limits CPU and memory usage on some DBs (and IO in SQL Server 2014) like search DBs Allow less CPU & mem & IO usage during work hours Allow more CPU & mem & IO usage during off hours
- 47. 10 simple tips to maximize performance http://www.sharepointblog.no/?p=85 1. SSD Disk or better 2. Formating disk with 64K 3. Language corralation Latin_CI_AS_KS_WS 4. Maximum memory 5. Changed Sizes on Model database 6. Default fill factor to 80 7. Switched of autocreate statistics 8. Max Degree of Parallelism – set to 1 (it has to be) 9. Changed Initial Size & Autogrow on temp database, and created extra temp files for the amount of processors. 10. Don’t do backups at midnight.
