Whichever way you try to dress it up, SQL Server’s decay curve has never been one that could be described as being graceful. Bottlenecks through disk, memory, CPU or incorrect indexing can quickly compound resulting in significant reductions in system performance, affecting application responsiveness and slowing business intelligence decision making.
Troubleshooting and identification of underlying root causes for SQL performance problems requires an in-depth understanding of the SQL server environment, its supporting infrastructure, operational workloads and knowledge into how the SQL compiler interprets and processes these workloads.
DBA Services’ SQL Server Performance tuning services can help your business quickly identify environment or database misconfigurations that could be harming your server’s performance. We also analyse over 100 hardware and SQL server specific performance counters that could be leading to hardware based bottlenecks.
SQL Server performance problems can often be fairly quickly identified and resolved, allowing your business to return to peak operational performance, and returning your staff back to peak productivity again.
Our database performance tuning service performs a thorough review of your SQL Server environment with a particular focus around key problem databases identified to us as part of the support service engagement. We’ll perform a detailed analysis of the problem through a review of SQL Server’s dynamic management views, looking at query execution paths of problem transactions to identify opportunities for index optimisation. We’ll also review your current index maintenance strategies to ensure these adhere to industry best practices.
We can also review your underlying hardware configuration through a 48 performance baseline, from which we can quantifiably identify whether there are any hardware based bottlenecks affecting your query performance and / or SQL Server’s operability in general. We have a proven track record of finding and resolving SQL performance issues, so there’s no further need to suffer at the hands of poor application performance. Our DBAs have the training and experience to get your SQL Server performing at it’s best again.
High Value Missing Indexes
SQL Server’s Dynamic Management Views allow us to review internal query statistics in (near) realtime in order to identify indexing issues such as high-value missing indexes or over-indexing within the database.
Review of Expensive Transactions
We review your top most expensive transactions both from a CPU and IO load perspective, and make recommendations for improving the performance of these.
Slow Query Monitoring
Using SQL Server’s extended events capabilities (or SQL profiler for older versions of SQL) we’re able to capture slow performing queries to find key problem areas within the environment’s transaction workloads.
SQL Query Execution Plan Analysis
Analysis of a query’s execution plan also provides valuable insights into expensive joins, where conditions, nested loops and other factors which can impact performance.
Review of Deadlocks and Lock Chains
Deadlocks and extended lock chains create major performance issues. While typically related to the race condition within the code, identification of these locks can help developers improve application logic to avoid these from occurring.
Top Wait Conditions
Review of top wait conditions can provide insights into external factors such as slow IO or even where applications are struggling to process data fast enough.
Performance Baseline Analysis
A comprehensive performance baseline which reviews a wide collection of hardware and SQL specific counters to help identify potential hardware based bottlenecks.
Tuning of SQL environment
Review of SQL Server configuration against industry best practice to ensure optimal configuration for OLTP vs OLAP transaction workloads.
