Performance Tuning |
Our experience in handling application performance problems of differing complexities and severities can help you overcome performance bottlenecks in your database, report and web application.
|
| Process |
- We understand your system performance requirement and the problem that you face
- The root cause affecting the performance of your system is identified, solutions are recommended to suit your requirement and available resources
- We then implement the solution and test the system performance to note the performance gain. This process could be iterative and the steps are repeated till the desired performance is achieved
Capabilities
Whatever the cause of bad performance - be it a poorly written SQL query or an inappropriate database design, or an ill-maintained database server - our team can resolve it for you. The following advantages enable us to serve you better and faster:
- Experience in working with database size as large as two terabytes
- Expertise in tools to monitor application performance and studying query plans
- A knowledge base of performance problems and solutions including best practices for writing SQL queries, procedures, database configuration and database design

Database performance tuning
Our database experts can provide performance solutions in the following technologies:
- MS SQL Server 2000/2005
- Oracle 8i, 9i, 10g
- Informix 10
We understand the differences in the nature of OLTP and OLAP applications and provide an entire range of services for tackling performance problems in both:
OLTP database
- Feature-level performance optimization by checking transaction isolation level, database locking and contention issue, index utilization and query tuning
- Application-level performance optimization by implementing normalization and partitioning
- Database-level performance optimization by maintaining up-to-date table/index statistics, performing table/index de-fragmentation, data archival and customizing database configuration
OLAP database
- Report-level performance optimization by query tuning, employing derived reporting table, indexed or materialized view, resolving locking problem and rationalizing temporary table usage
- Application-level performance optimization by implementing dimensional modeling, de-normalization, indexing and partitioning in the analysis database
- Database-level performance optimization by maintaining up-to-date table/index statistics, table/index de-fragmentation, distributing data across files and files across drives, parallel processing, evaluate and recommend CPU upgrade, evaluate and recommend Memory upgrade, server upgrade
Report performance tuning
- Crystal Reports
- SQL Server Reporting Services
Report performance tuning
- ASP, .NET based web application
